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

Khalid Ahmed d34868e693 adding phy_procedures_nrUE_TX to ulsim 
- adding SCHED_NR_UE_LIB to ulsim compilation library
- fixing linking compilation problems
- using fapi_nr_dci_pdu_rel15_t struct to initialize PUSCH
- test_input random data is set in phy_procedures_nrUE_TX instead of ulsim

Ahmed Hussein 176d873083 Shifting the QAM threshold by AMP, instead of shifting the data by AMP_SHIFT
