Ahmed Hussein 53e6a5223c Minor Fixes in ulsim 2019-08-23 16:08:57 +02:00
Ahmed Hussein f398e4999b Set start_rb to 0 
- start_rb was set to 30, and nb_rb was set to 50 with NB_RB_DL = 106.
- When the DC subcarrier is included in the RB allocation,
  this causes errors in FFT/IFFT operations arounf the DC subcarrier
- This leads to errors in unscrambling and decoding

Ahmed Hussein abfd072376 channel estimation, compensation, etc .. 
Added the following folder:
- ../openair1/PHY/NR_ESTIMATION/

Added the following file to CMakelists.txt:
- ../openair1/PHY/NR_ESTIMATION/nr_ul_channel_estimation.c

Added the following functions:
- nr_pusch_dmrs_rx
- nr_gold_pusch
- nr_ulsch_channel_level
- nr_ulsch_channel_compensation
- nr_ulsch_scale_channel is commented out (I think only used for downlink)

Changes from Khalid Ahmed Mahmoud Mohamed:
- nr_pusch_channel_estimation is used
- nr_ulsch_scale_channel is used
- nr_ulsch_channel_level is used
- nr_ulsch_channel_compensation is used
- multiple logging options for channel and signal magnitude

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
