lukashov 42eb48faa7 Fixing previous commit: messed up with parenthesis in dlsch_demodulation.c 2016-01-08 15:32:53 +01:00
Florian Kaltenberger 6011553117 fixing issue 71 (bug in freq_channel) 2016-01-08 12:02:42 +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).

lukashov 80cb191214 Now channel-level dependent part of log2_approx works properly. 
Validating mcs-dependent shift.

lukashov 3262bfa66e Fixing dlsch_channel_level_TM34. 
Passing 2 avrage channel lvel and not max how it was done before.
Continuing with calibration.
