FPGA implementation of OTFS modulation communication system

Abstract

Orthogonal Time Frequency Space (OTFS) modulation has emerged as a promising waveform for next-generation wireless communication systems, particularly in highly dynamic environments where conventional Orthogonal Frequency Division Multiplexing (OFDM) suffers from severe Doppler effects. This thesis presents an FPGA-based implementation of OTFS modulation and demodulation, focusing on the efficient realization of key signal processing components. The proposed FPGA design successfully implements the key signal processing modules of an OTFS transceiver while optimizing computational efficiency and resource utilization. Functional verification confirms the correctness of data transmission and reception, as well as frame synchronization. Performance analysis indicates that the system meets real-time processing requirements, with optimization strategies effectively balancing speed and hardware resources. This work demonstrates the feasibility of OTFS implementation on FPGA and provides insights for future improvements, such as enhanced synchronization strategies, parallel processing techniques, and integration with advanced detection algorithms to further optimize performance in dynamic wireless environments.
