gauthier 574399fa43 some formatting changes in physcope for eNodeB. fixes for joint SR/ACK-NAK detection. 2016-01-06 16:33:04 +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
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
Rohit Gupta 8e1b5d26d4 doxygen support for USRP PHY Interface 2015-12-31 09:06:10 +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

Cedric Roux 3d0a6e4032 fix a bug in dot_product. The return was done before _mm_empty() 2015-12-22 13:28:05 +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. Placement of RA allocations at PRB 0-3. Tested DL throughput on 5 MHz to 16 Mbit/s in TM1. 2015-12-21 19:05:28 +01:00

Raymond Knopp 1e08469ed8 conversion of some sse4 code to avx2 for turbo encoder. No noticeable improvement (output expansion for encoder doesn't benefit much because of unpack instruction difference on AVX2. 
maxh adjustement in dlsch_demodulation (to be checked further for other mcs)
