2013-06-24umtrx: flush any possible garbage bursts at startThomas Tsou1-5/+7
In certain cases (higher sample-per-symbol counts), there is some sensitivity to either timeouts or bad metadata on the first packet. The first packet sets the transceiver clock, so this is essential. As a workaround, drop the first 50 packets to guarantee that we get a packet with a valid timestamp Signed-off-by: Thomas Tsou <ttsou@vt.edu>

2013-04-04Transceiver52M: Fix calculation of TS correlation for 2 sps and higherttsou1-2/+2
The correlation starting point for normal burst training sequence calculation should be a scaled value of the same symbol regardless of the samples-per-symbol used. Use of 2 samples-per-symbols double the index values, but yields the following outputs, which results in a late time-of-arrival value at the output of the correlation. This patch modifies the parameter calculation accordingly. 1 sps parameters maxTOA = 3 spanTOA = 5; startIx = 61; endIx = 87; windowLen = 26; corrLen = 7; 2 sps parameters (errant case) maxTOA = 6; spanTOA = 10; startIx = 112; endIx = 184; windowLen = 72; corrLen =13; 2 sps parameters (corrected) maxTOA = 6; spanTOA = 10; startIx = 122; endIx = 174; windowLen = 52; corrLen =13; Signed-off-by: Thomas Tsou <tom@tsou.cc> git-svn-id: http://wush.net/svn/range/software/public/openbts/trunk@5183 19bc5d8c-e614-43d4-8b26-e1612bc8e597

2012-12-06transceiver52m: reset energy threshold on receive gain changesttsou1-1/+4
The adaptive energy detection threshold does not scale relative to signal level. In other words, the adjustment factor will be the same whether the at 40% of signal level or 4%. If the receive gain is reduced by a large amount, suppose 20 dB, the receiver may take minutes to adjust to the new level. When the receive gain is changed, reset the threshold back to the initial level. This reduces issues of runtime gain adjustment and prevents blocking bursts while the threhold level slowly adjusts.

2012-11-23Alexander's patches:kurtis.heimerl3-5/+4
1)I did an experiment and compiled OpenBTS with clang yesterday, which immediately highlighted two potential bugs in the Transceiver52 code. I'm not sure they are indeed bugs and not the intended behavior, but they look very much like that. The first one is below and the second one is in the following mail. GSM::Time() arguments are defined like #define USB_LATENCY_INTRVL (10,0), which means that they are expanded into GSM::Time((10,0)). This expression is a GSM::Time() with a single parameter where (10,0) return value of the last argument, 0 in this case. I.e. GSM::Time((10,0)) is equivalent to GSM::Time(0). I think this was not the intention. 2) Printing \n after every complex number breaks output when you want to print it in a single line, e.g. in many debug output. I do not claim any copyright over this change, as it's very basic. Looking forward to see it merged into mainline. git-svn-id: http://wush.net/svn/range/software/public/openbts/trunk@4515 19bc5d8c-e614-43d4-8b26-e1612bc8e597

r4232: Major change in hos entries are removed from a TransactionTable. >From now on, the only place were entries are actually removed is in TransactionTable::innerRemove. Anywhere else, the remove methods just set a flag to tag the entry for later removal be innerRemove. This allows us to survive situations where we try to touch transactions that have been removed already. We still log at the ERR level, but no more segfaults. Updated all of the TransactionTable "find" methods to not return pointers to dead or removed tranactions. Updated find-by-channel search to return the transaction entry with the highest transaction number, which fixes a bug that sometimes picked up the wrong transaction records during EA TCH assignment. r4253: New exception class for when someone tries to use a "removed" transaction. r4254: Updated copyright notice. r4265: Unlock TransactionEntry::mLock while blocked on SIP message FIFOs in SIPEngine. This does wonders to reduce lock contention and make everything more snappy. Use Mutex::tryLock in TransactionEntry::dead and if lock is held, assume that it is not dead. This also does a lot to reduce lock contention. r4294: Change Um congestion response back to SIP 503. r4295: When deleting an entry that has failed to respond to paging, send a SIP 480 response so the switch knows that transaction is dead. r4412: Fixed bug that was causing SIPInterface to crash when the IMSI cannot be extracted from the To: header. git-svn-id: http://wush.net/svn/range/software/public/openbts/trunk@4497 19bc5d8c-e614-43d4-8b26-e1612bc8e597

2012-10-22Transceiver52M: UHD: Setup option to pass arguments from command linettsou6-10/+22
UHD accepts optional 'args' that can be used for device descriptions such as IP address, device type, etc. Allow these to be passed in on the transceiver command line as the third argument (number of supported carriers is the second argument). This option benefits those who may have multiple UHD devices attached to a single system. This option is not yet supported by GSM core and requires starting the transceiver independently on the command line. This option has no effect when USRP1 is used.

2012-08-08transceiver: uhd: prevent output of underrun message at ERROR levelttsou1-4/+8
The appearance of underruns on B100 due to the latency transmit window scares people. These should not be logged at ERROR level because the events are generally not real errors. So use the same behaviour of USRP1 of not logging these events. The presence of underrun events can be determined by changes in the latency window that is shown with log level set at INFO.

2012-08-08transceiver: uhd: allow underrun flag to reset during timing alignmentttsou1-1/+1
Allowing the underrun flag to reset will prevent a single event from causing large jumps in the transmit latency threshold. This should keep unreasonable timing latencies from occurring (e.g. latencies of 20+ frames). git-svn-id: http://wush.net/svn/range/software/public/openbts/trunk@3981 19bc5d8c-e614-43d4-8b26-e1612bc8e597
2012-08-08transceiver: b100: raise minimum transmit latency valuettsou1-3/+13
Put a floor on the transmit latency of the B100 in order to suppress underruns in typical conditions. Empirical data from a handful of relatively recent machines shows that the B100 will underrun when the transmit threshold is reduced to a time of 6 and a half frames, so we set a minimum 7 frame threshold. The overall benefit should be marginal and may increase the possibility of bursts arriving stale (after the trasmit deadline), but will reduce the number of alarming UHD related messages that appear in the log file. This patch is UHD and B100 specific - USRP1 is unaffected.
