Abstract

Abstract

Orthogonal Time Sequency Multiplexing (OTSM) is a low-complexity modulation method suitable for high-speed mobile scenarios. However, a single waveform design method is difficult to meet diverse application requirements and performance demands. Therefore, on basis of Weighted FRactional Fourier Transform (WFRFT), a Weighted FRactional Walsh-Hadamard Transform (WFRWHT) is proposed and an integrated WFRFT-WFRWHT-OTSM waveform framework based on multidimensional extensions is put forward. Through the flexible configuration of two-dimensional parameters, this framework can be degraded to different waveforms such as OTSM, orthogonal time-frequency-space, hybrid carrier, orthogonal frequency division multiplexing and single carrier. In addition, Bit Error Rate (BER) and Peak-to-Average Power Ratio (PAPR) performances of the integrated WFRFT-WFRWHT-OTSM framework over delay-Doppler channels are studied with Gauss-Seidel (GS) iteration equalization. Simulation results show that the proposed framework achieves better BER and PAPR performances through changing the order of WFRFT and WFRWHT over different delay-Doppler channels.
