      Remove UESIM_EXPANSION · 4c7035e6
      Robert Schmidt authored
      This completely removes the UESIM_EXPANSION define: it does not compile
      at the moment. Its function was to multiplex multiple UEs on the same
      TUN interface. However, this functionality is not needed since it is
      possible to allocate many TUN devices (i.e., >= 32).

      Common Phase error estimation and compensation in uplink. · b288eafd
      Parminder Singh authored
      FEATURE STATEMENT:
      - Introduce linear phase error noise model in Uplink at UE
      - Perform common phase error (CPE) estimation and compensation at gNB
      
      SOLUTION:
      - A linear phase shift model is introduced in simulation.
      - PTRS symbols are used to perform estimation of CPE from DMRS compensated signal
      - The estimated values are interpolated in time domain and signal is compensated for the CPE.
      - PTRS processing is done in Frequency Domain for each symbol in a slot and
        LLR's are calculated for each symbol accordingly.
      
      IMPLEMENTATION:
      * sim.h/channle_sim.c
      - Linear Phase Noise Generation model definition.
      * nr_ul_channel_estimation.c/nr_ul_estimation.h
      - CPE estimation from PTRS and DMRS compensated signal.
      * nr_dmrs_rx.c/nr_refsig.h
      - Regenerate PTRS symbols at gNB.
      * nr_ulsch_demodulation.c
      - Removed old PTRS processing code and move to a common PTRS processing function
      * defs_gNB.h/init.c
      - New PTRS variables definition and initialization
      * nr_ulsch_ue.c
      - Corrected PTRS parameter to get new PTRS symbols for each OFDM symbol
      
      TESTING
      * ulsim.c
      - Added Phase noise, Enable PTRS signal and verified the output.
      
      VERIFICATION
      - The LLR are rotated back with estimated CPE and no error is observed in scrambling/decoding
