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.

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 ------------------------- DATA-SPECIFIC INFORMATION ------------------------- Variable list, defining any abbreviations, units of measure, codes or symbols used: BER is the Bit Error Ratio SNR is the Signal to Noise Ratio Eb/N0 is the Energy to Noise power ratio RMSE is the Root Mean Square Error CRB is the Cramér-Rao Bound MMSE is Minimum Mean Square Error, which in this case is a channel equalisation method OFDM is Orthogonal Frequency-Division Multiplexing OTFS is Orthogonal Time Frequency Space AFDM is Affine Frequency Division Multiplexing IM is Index Modulation CDMA is Code Division Multiple Access Dl-CDMA-OTFS is CDMA applied along the delay axis of OTFS Dp-CDMA-OTFS is CDMA applied along the Doppler axis of OTFS DD-CDMA-OTFS is CDMA applied along both the delay and Doppler axes of OTFS RSC is Recursive Systematic Convolutional, which is a channel coding method URC is Unity Rate Convolutional, which is a channel coding method The thesis contains the full list of abbreviations and acronyms used.
