2019-07-01Introduce structs to encode TRXD packetsPau Espin Pedrol1-1/+3
This will ease adding new protocol versions in the future. Related: OS#4006 Change-Id: I67ffede171eddde436f9057191ed76015a8ea6eb
2019-05-06smpl_buf: Move it to device/common and create libdevice_common.laPau Espin Pedrol1-1/+1
Since in next commit osmo-trx-lms starts using smpl_buf.cpp, it seems some automake step doesn't like including a cpp file twice from a different directory, since race conditions can occur building it. Instead we define the dependency by first building a static lib and then using it on each libdevice.la (one per device type). We already do the similar under arch/ subdir, where we have a common/ subdir and then one subdir and lib per architecture. Change-Id: I465ad0f6d5569bb3006d711c8fd0df14391fcf35
2018-06-13lms: Makefile.am: Reorder params to fix link issuePau Espin Pedrol1-2/+2
It seems the order in which static code and -lfoo is passed to the linker matters. This commit is a lms specific follow-up of commit 2a8183bdf0dfd5c5a59c3933fb932e827ddf811c. Change-Id: I59c20d268ecac4c22689124165c47295bd9176d4

2018-04-24Build one osmo-trx binary for each device support enabledPau Espin Pedrol1-10/+15
Same way as we do in osmo-bts. After this commit, osmo-trx no longer exists. Instead, osmo-trx-uhd and osmo-trx-usrp1 are generated based on configure flags enabled. A new flag --with(out)-uhd has been added to enable/disable build of osmo-trx with UHD backend. It is left enabled by default to keep compatibility with older build scripts. Binary with USRP1 backend must still be manually enabled with --with-usrp1 flag. Change-Id: Iea8c0d7434762713a53440d29bf3ebd84accb262

2018-03-07Makefile.am: Avoid using subdir if arch is not requiredPau Espin Pedrol1-1/+5
There's no need in going a level deeper if we already know nothing's going to be done. This way we also get cleaner make outputs.

2017-05-19radioInterface: Remove UmTRX 'diversity' optionTom Tsou1-2/+1
The 'diversity' option was an experimental 2 antenna receiver implementation for UmTRX. The implementation has not been maintained and current working status is unknown. In addition to code rot, Coverity is triggering errors in the associated code sections. Removal of code cleans up many cases of special handling that were necessary to accommodate the implementation.

2016-07-01mcbts: Add multi-ARFCN radio supportTom Tsou1-0/+1
Add new radio interface "radioInterfaceMulti" for multi-carrier support. Only USRP B200/B210 devices are supported because of sample rate requirements (3.2 Msps). Only 4 SPS operation Tx/RX is supported. 8-PSK is supported. Other options may be added at a later time Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-01mcbts: Add multi-ARFCN channelizing filtersTom Tsou1-3/+11
Introduce polyphase channelizer (Rx) and synthesis (Tx) filterbanks, which serve as the signal processing backend for multi-carrier GSM. Fast Fourier Transform (FFT) is used internally. FFTW is added as a new build dependency. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-01iface: Add inner ring-buffer implementationTom Tsou1-0/+2
Two buffers, inner and outer, are used in the transceiver implementation. The outer buffer interfaces with the device receive interface to guarantee timestamp aligned and contiguously allocated sample buffers. The inner buffer absorbs vector size differences between GSM bursts (156 or 157 samples) and the resampler interface (typically fixed multiples of 65). Reimplement the inner buffer with a ring buffer that allows fixed size segments on the outer (resampler) portion and variable lengths (GSM side) on the inner side. Compared to the previous stack-like version, this implementation removes unnecessary copying of buffer contents. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-06-22makefile: Fix build from an external path.Alexander Chemeris1-1/+1

2013-11-16Transceiver52M: Create new osmo-trx executableThomas Tsou1-6/+5
Create new main executable with full command line option parsing of relevant parameters. Database configuration table still exists (and must exist because of the global gConfig object), but can be bypassed with command line options. Signed-off-by: Thomas Tsou <tom@tsou.cc>
2013-11-15Transceiver52M: Enable all warnings and resolveThomas Tsou1-1/+1
Mainly basic signed vs unsigned comparisons and intializer ordering. Signed-off-by: Thomas Tsou <tom@tsou.cc>
2013-11-15Transceiver52M: Add dual channel diversity receiver optionThomas Tsou1-1/+2
This patch add support for dual channel diversity on the receive path. This allows two antennas two shared antennas to be used for each ARFCN handling channel in the receiver. This configuration may improvde performance in multi-path fading environments, however, noise andpotential interference levels are increased due to the higher bandwidth used. The receive path is oversampled by a factor of four for a rate of 1.083333 Msps. If the receive paths are tuned within a maximum channel spacing (currently set at 600 kHz), then both ARFCN frequencies are processed by each channel of the receiver. Otherwise, the frequency shifted diversity path is disabled and standard non-diversity operation takes place. Diversity processing is handled by selecting the path with the higheset energy level and discarding the burst on the second path. Selection occurs on a burst-by-burst basis.

2013-11-15Transceiver52M: Add ARM NEON supportThomas Tsou1-2/+7
Similar to the existing Intel SSE cases, add support for NEON vector floating point SIMD processing. In this case, use ARM assembly directly as the NEON intrinsics do not generate preferential code output. Currently support NEON vectorized convolution and floating point integer conversions.

2013-11-08Transceiver52M: Remove unused files and utilitiesThomas Tsou1-24/+2

2013-11-04build: Set UHD driver as default configurationThomas Tsou1-26/+8
Currently the default configuration is to not build the full transceiver, which is pointless. Set the UHD driver, which includes either Ettus or Fairwaves variants, as the default. Signed-off-by: Thomas Tsou <tom@tsou.cc>

Convertions are performed in multiples of 4 or 8. All loads are considered unaligned. Signed-off-by: Thomas Tsou <tom@tsou.cc>
2013-10-18Transceiver52M: Replace resampler with SSE enabled implementationThomas Tsou1-0/+2
Replace the polyphase filter and resampler with a separate implementation using SSE enabled convolution. The USRP2 (including derived devices N200, N210) are the only supported devices that require sample rate conversion, so set the default resampling parameters for the 100 MHz FPGA clock. This changes the previous resampling ratios. 270.833 kHz -> 400 kHz (65 / 96) 270.833 kHz -> 390.625 kHz (52 / 75) The new resampling factor uses a USRP resampling factor of 256 instead of 250. On the device, this allows two halfband filters to be used rather than one. The end result is reduced distortial and aliasing effecits from CIC filter rolloff. B100 and USRP1 will no be supported at 400 ksps with these changes. Signed-off-by: Thomas Tsou <tom@tsou.cc>
2013-10-18Transceiver52M: Replace convolve and related calls with SSE implementationThomas Tsou1-9/+10
This large patch replaced the convolve() call with an SSE vector enabled version. The lower C and SSE intrinsic based code operates on fixed and aligned vectors for the filter taps. The storage format of interleaved I/Q for both complex and real vectors is maintained. SSE filter tap values must: 1. Start 16-byte aligned 2. Number with a multiple of 4 between 4 and 20 for real taps 3. Number with a multiple of 4 for complex taps Non-compliant values will fall back to non-SSE usage. Fixed length iterators mean that head and tail cases may require reallocation of the input vector, which is automatically handled by the upper C++ interface. Other calls are affected by these changes and adjusted or rewritten accordingly. The underlying algorithms, however, are unchanged. generateGSMPulse() analyzeTrafficBurst() detectRACHBurst() Intel SSE configuration is automatically detected and configured at build time with Autoconf macros.

2013-10-18Transceiver52M: Set resampling option automatically based on deviceThomas Tsou1-7/+1
Remove the built time resampling selection and link both options. Move the normal push/pullBuffer() calls back to the base class and overload them in the inherited resampling class. USRP2/N2xx devices are the only devices that require resampling so return that resampling is necessary on the device open(), which is the point at which the device type will be known. The GSM transceiver only operates at a whole number multiple of the GSM rate and doesn't care about the actual device rate and if resampling is used. Therefore GSM specific portion of the transceiver should only need to submit the samples-per-symbol value to the device interface. Then, the device should be able to determine the appropriate sample rate (400 ksps or 270.833 ksps) and if resampling is appropriate. Signed-off-by: Thomas Tsou <tom@tsou.cc>

2011-11-26transceiver, resamp: insert missing filter valueskurtis.heimerl1-1/+3
With transceiver integration, the resampling filter files were dropped.
