The next-generation wireless communication sys-tems require available bandwidth, reliability, and mobility. How-ever, the wider bandwidth and higher carrier frequency pose challenges for communication systems, including stricter peak-to-average power ratio (PAPR) requirements and more severe Doppler effects. This paper introduces an enhanced discrete Fourier transform spread (ED-OTFS) waveform that utilizes head-tail insertion sequences and frequency domain spectrum shaping (FDSS) methods to mitigate multipath delay variations and reduce high PAPR. Additionally, a reliable channel equalization algorithm for the ED-OTFS receiver is designed to mitigate the impact of the Doppler shift. Simulation results demonstrate that the proposed waveform significantly improves the bit error rate (BER) and PAPR performance compared with the existing schemes.
