lukashov cbd30e62fa Experimanetal change in dlsch_channel_commensation_TM34. Will not work for more than 2 antennas.
Testing.

lukashov 388452f1bc For in demodulation TM4 trying average as a sum of energy in both antennas.
Changing names of output files in dlsim respectiively.

Florian Kaltenberger 6011553117 fixing issue 71 (bug in freq_channel) 2016-01-08 12:02:42 +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).
