lukashov bbb369a937 Small bugfix for TM5 and TM6 2016-01-08 15:53:41 +01:00
lukashov 42eb48faa7 Fixing previous commit: messed up with parenthesis in dlsch_demodulation.c 2016-01-08 15:32:53 +01:00
Raymond Knopp ee1d0d56ad added noise-figure trace in stats. 2016-01-07 17:38:56 +01:00
lukashov b80a6660bf Some more clean up in dlsch_demodulation.c 2016-01-07 13:50:45 +01:00
lukashov 3521765b62 Changes: 
1. Fixing a bug in dlsch_channel_level_TM56.
avg128D = _mm_setzero_si128() must be done inside the rx_antennas loop and not before

2. Cleaning up code in dlsch_demodulation.c

3. Offsets for TM5 and TM6 still must be validated.

4. Right now IA and I-UA receivers for TM4 have the same offset -
validate if any additional penalty/gain is needed.

5. Shortened file names in dlsim.c since matlab can read only 63-characters file names.

6. Tested: TM4 U2 -gS perfect CE works fine for EESM and MIESM abstraction (MCS 4 MSE= 0.007 dB on both streams).

gauthier e44146b708 handling of timing advance is improved. MAC retrieves timing advance from phy once prior to DL scheduling and clears the statistic in PHY. A timer for controlling the timing advance periodicity was introduced. 2016-01-06 11:37:26 +01:00
lukashov 3262bfa66e Fixing dlsch_channel_level_TM34. 
Passing 2 avrage channel lvel and not max how it was done before.

Raymond Knopp 8d4405bddf added avx2 optimized turbo decoder for 16-bit LLR. This decoder parallelizes by decoding 2 code segments concurrently. requires updates dlsch_decoding.c to identify when new parallel version can be used. other minor changes related to memory allocations for future avx2 optimizations (32-byte alignment). 2016-01-03 15:15:26 -08:00
