Performance analysis of novel decoding techniques of OTFS

Orthogonal Time Frequency Space (OTFS) is being sparse in nature. The work aims to implement various sparse signal recovery algorithms from various categories like Basis Pursuit, Orthogonal matching pursuit and Weak Matching Pursuit (WMP) to reconstruct an OTFS signal which will help us in further reducing the complexity of demodulation process. The plots for Bit error rate performance for conventional OTFS and all of its variants like ZP OTFS, RZP OTFS, CP OTFS and RCP OTFS has been simulated and analysed.
