Florian Kaltenberger f0982d3147 small performance improvements for perfect channel estimation in dlsim 2016-01-08 15:44:52 +01:00
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).

lukashov 170291413d Going back to fixed shift in log2_approx for TM4. Playing with computing the channel average in order to find optimal shift. 2016-01-04 14:33:01 +01:00
Raymond Knopp 7f53f84c00 Tested modifications for 23.04 Ms/s 100 PRB transmission/reception (Downlink). This will reduce I/Q acquisition times for 20 MHz channels. new option in dlsim (-E) for testing 1536-point DFT instead of 2048 for this lower sampling rate. Added normalization to idft1536. Should also be added to dft1536 later. 2015-12-29 20:34:47 +01:00
