Florian Kaltenberger f0982d3147 small performance improvements for perfect channel estimation in dlsim 2016-01-08 15:44:52 +01:00
lukashov 42eb48faa7 Fixing previous commit: messed up with parenthesis in dlsch_demodulation.c 2016-01-08 15:32:53 +01:00
Florian Kaltenberger 6011553117 fixing issue 71 (bug in freq_channel) 2016-01-08 12:02:42 +01:00
Raymond Knopp ee1d0d56ad added noise-figure trace in stats. 2016-01-07 17:38:56 +01:00
lukashov b80a6660bf Some more clean up in dlsch_demodulation.c 2016-01-07 13:50:45 +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).

gauthier 574399fa43 some formatting changes in physcope for eNodeB. fixes for joint SR/ACK-NAK detection. 2016-01-06 16:33:04 +01:00
lukashov 80cb191214 Now channel-level dependent part of log2_approx works properly. 
Validating mcs-dependent shift.
 2016-01-06 13:07:10 +01:00
gauthier e44146b708 handling of timing advance is improved. MAC retrieves timing advance from phy once prior to DL scheduling and clears the statistic in PHY. A timer for controlling the timing advance periodicity was introduced. 2016-01-06 11:37:26 +01:00
lukashov 3262bfa66e Fixing dlsch_channel_level_TM34. 
Passing 2 avrage channel lvel and not max how it was done before.
Continuing with calibration.

lukashov 7a8e3a421c Commit to compare -u0 and -u2 performance in interference free environment for 
TM4 and verify if any additional gain/penatly is needed.

Raymond Knopp 8d4405bddf added avx2 optimized turbo decoder for 16-bit LLR. This decoder parallelizes by decoding 2 code segments concurrently. requires updates dlsch_decoding.c to identify when new parallel version can be used. other minor changes related to memory allocations for future avx2 optimizations (32-byte alignment). 2016-01-03 15:15:26 -08:00
Raymond Knopp 27b1707ed1 AVX2 updates to turbo encoder interleaver. Also speedup in RSC encoder. 40% speedup improvement. 2016-01-01 05:51:09 -08:00

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

gauthier cf8645d8cd Limitation of non SI DLSCH allocations in subframe 0/5 to PRBS not around DC (avoid puncturing from PBCH). Placement of SI around DC instead of randomized allocations.
