Progress

  • This week:
    • Basic C++ transmitter implementation (1x1 working, 2x1 testing)
    • Debug MIMO detection issues (Adjustments)
  • Next week:
    • Nx1 MIMO C++ transmitter
    • Learn about NOMA in parallel MIMO architecture

FlexCore Methods

  • find_top_position_vectors PASSED
    • compute_path_probability PASSED (restructured)
    • expand_position_vector PASSED (fixed issue)
  • map_position_vector_to_symbol PASSED
    • get_approximated_sorted_symbol WIP

​

So, we are finding better answers (than before) but not the best answer (might be due to lack of FEC)
