METHODOLOGICAL INFORMATION
--------------------------

Description of methods used for collection/generation of data: All the sensing RMSE simulations and the "Coded_Soft-MMSE_AFDM" communication simulations were run for a set number of frames. For the "Additional_Schemes", "IM-OFDM_ISAC", and "CDMA-OTFS_ISAC" communication BER simulations, a minimum number of frames and errors were set, as well as a maximum number of simulated bits for each Signal to Noise Ratio (SNR) or Energy to Noise power ratio (Eb/N0). The simulations for a set SNR or Eb/N0 stop when the minimum number of frames and errors have been reached, or the maximum number of bits have been simulated. Information is also provided in the thesis and the following publications:

Methods for processing the data: The data is directly generated by the code that was run. The data has then been copied and collated into the .csv files in this submission.

Describe any quality-assurance procedures performed on the data: Tested different simulation lengths to determine that the results are representative. The relevant results have also been compared with other published data and internal studies.

People involved with sample collection, processing, analysis and/or submission: Supervisors Prof. Lajos Hanzo, Prof. Lie-Liang Yang, and Dr. Chao Xu
