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).
