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

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.

Melissa Elkadi 4dd579e042 int32_t to c16_t conversion 
This commit includes changes to the function
footprints for vaiours NR UE and gNB functions.
It does not updated the LTE code. For functions
shared by both LTE and 5G, we maintained the original
LTE footprint and argument structure.

Several of the simulators that use these functions
have been updated as well. The specific usage of these
functions which index into the int32_t buffers and
treat the first int16_t and the real and the second
as the complex should be modified in the near future.

Ahmed Hussein 10e3a299be Restructuring "nr_slot_fep_ul"

Ahmed Hussein 02e329a35d SC-FDMA working for 1 SNR loop (enabled using "NR_SC_FDMA" MACRO) 
- Added nr_dft at UE side and nr_idft at gNB side
- NR_SC_FDMA can be found in "PHY/defs_nr_common.h"
- For 1 SNR loop, the code executes correctly
- For more loops, it gives a segmentation fault in the LDPC decoder
- The segmentation fault is caused when nr_idft is used
- The code works fine when the "NR_SC_FDMA" is disabled
