2017-03-28sigProcLib: Constify demodulation functions burst argument.Alexander Chemeris2-10/+10
demodCommon() used to scale input vector in place which changed original data. That's a bad practice and is not really necessary, so I've changed the code to scale burst after it's copied to a new vector during a delay operation. Change-Id: Ic45f71b634e48808356d68925bb9f5783e0bf0d3

2017-03-22BitVector: Convert SoftVector from 0..1 to -1..+1 soft bits.Alexander Chemeris2-13/+13
This makes code simpler and will allow us send -127..127 soft bits towards osmo-bts instead of 0..255 bits. Change-Id: I16ecc3d4c829dcf0f619ad995bc9d4a4ed8af0a4
2017-03-22BitVector: Remove convolutional codec - we don't use it in osmo-trx.Alexander Chemeris3-411/+1
Now we have more fexibility in how we represent SoftVector, since we no longer depend on the particular convolutional codec implementation. Change-Id: I3006b6a26c5eff59dbe9c034f689961802f1d0d0

2017-03-22Call vectorSlicer() right before packing bits for transmission to osmo-bts.Alexander Chemeris2-3/+3
vectorSlicer() converts soft-bits from -1..+1 to 0..1 while we want to keep SoftVector in -1..+1 mode until the last minute, because at some point we'll want to transmit -1..+1 to osmo-bts instead of converting it from 0..1 back to -1..+1 on the osmo-bts side. Plus it removes code duplication - we call it once instead of twice. Change-Id: Idd6ddd7ac219afb0df055a692632678b66373764
2017-03-22sigProcLib: Slice SoftVector instead of signalVector for GMSK demod.Alexander Chemeris2-26/+22
This makes it similar to 8-PSK demod and also saves a bit of lines ofcode and should give us a tiny improvement in performance. Ideally we need to remove vector slicing at all, because in osmo-bts-trx we convert back to +-1.0 again (actually to +-127, but it doesn't mater). So we should rather transmit +-1.0 values to avoid double conversion. Change-Id: If9ed6f0f80fbe88c994b2f9c3cae91d0d57f4442

2017-03-20sigProcLib: Fix documentation, sync argument names in .cpp and .h files.Alexander Chemeris2-47/+49
Documentation in sigProcLib.h was noticeably out of sync with the actual implementation - e.g. not all arguments were documented and arguments which are already removed are still in the documentation. Also argument names were different between declaration in .h and implementation in .cpp which was confusing. I've fixed this for detect*Burst() functions.

2017-03-07uhd: Increase MC-BTS FPGA clock rate to 51.2 MHzTom Tsou1-10/+13
Addresses following issues where UHD 3.9 and likely other UHD versions would report a master clock (FPGA) rate error. Update MC-BTS FPGA clock for B200 and B210 to 51.2 MHz, which is supported by all UHD versions. Only B200/B210 is supported for MC-BTS operation. https://osmocom.org/issues/1963 https://osmocom.org/issues/1648 ALERT UHDDevice.cpp:548:set_master_clk: Failed to set master clock rate ALERT UHDDevice.cpp:549:set_master_clk: Requested clock rate 3.2e+06 ALERT UHDDevice.cpp:550:set_master_clk: Actual clock rate 5e+06 Change-Id: I78fb2c0959abd0e666628ba39f433162aafb067e

2017-01-19Revert "uhd: Set minimum supported version to 3.9.0"Tom Tsou2-2/+11
This reverts commit 93ca09ea61d044e5f8662b28bf084c808cac4f2c. Ettus Research recommends the use of 3.9 series of UHD releases, but requiring this version has lead to issues with broken OBS and packaged binaries by Debian, Ubuntu, and other distributions.

Versions of UHD prior to 3.9.0 are no longer supported. Rather then backport and ifdef UHD version specific API and behavioral changes, set minimum support to the current LTS release, which is 3.9.0. Change-Id: Id7d15b52cd4e45f1d856a6ef3a84832a28f2dd04 Signed-off-by: Tom Tsou <tom.tsou@ettus.com>

Invert the initial and trailing diffential bits in the 4 sps GMSK modulator to fix power-time mask irregularity at start and end of burst. GSM tail bits are always zero, so we can safely use fixed bit values. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>

2016-07-19sigproc: Fix missing 8-PSK tail symbolsTom Tsou1-1/+1
Agilent E4406A measurement of TSC synchronized RF envelope measurement. showed failing power levels at the tail end of EDGE bursts. Regression traced back to following commit. Commit d2b070369dd5341ac42ec091370d8bcd5a8ac5ee "uhd: Correct timing alignment in 8-PSK and GMSK downlink bursts" In the patch, the EDGE burst was delayed one symbol, but erroneously truncated at the tail end causing the failing RF envelope measurement. The missing tail symbol did not appear to affect end-to-end EGPRS tests. This patch corrects the truncation. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-19transceiver: Fix 4 SPS receive TOA valueTom Tsou1-1/+1
The time-of-arrival (TOA) value out of sigProc is specified in symbols or, equivalently, 1 sample per symbol and does not need to be normalized. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-19transceiver: Fix mixed GSMK / 8-PSK transmissionTom Tsou1-1/+1
Input burst construction was declared static causing the first downlink burst from upstream to determine subsequent burst size and modulation. Consequently, fixed sequence EGPRS tests would pass, however, switching between 8-PSK and GMSK bursts would fail with only one modulation type being transmitted. Internally generated test sequences '-r' option were not affected because the bursts are not received through the socket interface. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-17uhd: Add command line option for GPS referenceTom Tsou5-13/+60
Unlike earlier versions of UHD, the current release (3.9.2) does not automatically select on-board GPSDO as the reference source. Modify the command line settings to allow explicit selection of GPS in addition to the external setting. Simultaneous GPS and external reference settingis disallowed.

2016-07-12UHD: Initial LimeSDR support.Alexander Chemeris1-1/+24
Only EDGE mode is currently supported. Traditional 1 SPS Rx / 4 SPS Tx mode requires different sampling rates which is not currently working. RF performance is also sub-optimal and requires more tuning.
2016-07-12radioInterface: Fix multi-channel buffer index bugTom Tsou1-1/+1
Discrete RF multi-channel was using hard coded buffer index on the channel iteration for transmit sample conversion. End result was segmentation fault on dual RF channel devices with both channels active (Ettus B210 and UmTRX). Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
2016-07-08mcbts: Allow out of order channel setupTom Tsou2-6/+9
Previous checks on multi-channel TSC and ARFCN settings would fail if channels were initialized out of order. Namely, if channel 0 was not configured first, osmo-trx would error on the control interface leading osmo-bts to fail. Allow global TSC setting on all channels with added logging notice. Notify if channel frequency is unexpected - which may happen if channels are setup out of order - but do no report as error. Signed-off-by: Tom Tsou <tom.tsou@ettus.com>
