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."
