Quency Lin fcb23b441a Refactor: Do SIMD precoding in a function 
Use blend instead of set and extract to rearrange, faster
Use 256 SIMD for every 2 RB, use 128 SIMD for ARM and last RB

Raymond Knopp a7bc282302 First-level of support for new aarch64 machines 
Testing on Neoverse N1 (Ampere 3GHz). Tested only on a subset of phy-simulators.

- Changes:
- use SIMDE consistently
- adaptations of LDPC decoder generator for ARMv8 performance
- SIMDe modifications of Intel CRC to allow for aarch64 build.
  optimizations for 128-bit to improve performance of LDPC encode/decode
  on aarch64 (Neoverse 1)
- added BG2 files for 128-bit ldpc encoder (aarch64)
- testing on Xeon
- testing on x86
- minor changes to build/run on x86
- change in crc.h after returning to aarch64
- removed some warning in ldpc decoder generator for x86_64
- char
- Delete irrelevant constants
- Correctly declare variables
- Define stdbool for all architectures
- Remove definition of _MM_SHUFFLE and use SIMDE_MM_SHUFFLE
- Remove commented code
- Fix CMakeLists.txt
- Include SIMDE avx2 functions in tools_defs.h

Laurent THOMAS 4c3d8e7581 fix-mem-overflow_64qam 
fix the 64QAM modulator case, that process 192 bits per iteration, then 24 bits per iteration of the tail bits, then added the last two symboles processing (no odd number of symbols case)

Robert Schmidt 555a54f85e Add Sidelink (SL) carrier frequency 
1. Adding a "SL" frequency for Sidelink mode. The
   importance of this variable is to ensure that
   when we are in mode 1 (UE+UE+gNB), that the slot
   configuration and frequencies do not overlap. This
   SL frequency is important for rotation and allows
   us to utilize the OFDM modulation and demodulation
   functions that already exist in OAI.
2. Adding sl_mode to the command line for proper UE
   deployment when in SL mode. sl_mode can be set to 0,
   1, or 2. sl_mode 0 indicates no-Sidelink at all,
   mode 1 is gNB, UE, and UE (3GPP defines mode numbers).
   sl_mode 2 indicated UE to UE communications with no
   gNB at all.
3. New functions for calculating the carrier frequency
   for SL mode.

Raymond Knopp bea3385f28 changes for ulsim to get functionality back. simulation behaviour for PUSCH is not good (BLER waterfall is way too steep even if SNR threshold is ok). Note develop does more or less the same thing but SNR threshold is lower. 2020-07-06 01:53:46 +02:00
