Streams must have the same shift, otherwise error floor. O
This reverts commit dbf587a5.

Bug in modulation.c with new qam tables. Error floor for 16QAM and 64QAM. Going back to old ones till fix the bug.

  avg_1[0] = avg_1[0] + avg_1[1];
Diff per-layer shift

Undoing previos commit. Previous commit is kept to generate TM4 PCE AWGN plots with the right precoder.

To be reverted after.

  avg_0[0] = avg_0[0] + avg_0[1];
  avg_1[0] = avg_1[0] + avg_1[1];
  avg_0[0] = max (avg_0[0], avg_1[0]);
  avg_1[0] = avg_0[0];

avg_1[0] = max(avg_1[0],avg_1[1]);

avg_1[0] = max(avg_0[1],avg_1[1]); taking this into account in correlation.

2) Fixing bug in mrc_TM4 - removing loop over tx antennas.

Fixing bug in passing arguments to dlsch_dual_stream_correlation, introducing dlsch_dual_stream_correlation_opposite

Revert "Experimanetal change in dlsch_channel_commensation_TM34. Will not work for more than 2 antennas."

Testing.

Changing names of output files in dlsim respectiively.

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).

Validating mcs-dependent shift.

Passing 2 avrage channel lvel and not max how it was done before.
Continuing with calibration.
