Abstract

This paper presents an innovative approach leveraging Spectrally Efficient Frequency Division Multiplexing (SEFDM) with enhancements, including Frequency Domain Cyclic Prefix (FDCP) and Modified Non-Linear (MNL) acceleration, to address challenges arising from delay and Doppler shift in mobile communication channels. Our methodology demonstrates superior performance and enhanced spectral efficiency while incurring minimal computational overhead. We conduct a rigorous evaluation of the SEFDM system model, examining the impact of the MNL acceleration on SEFDM detection, and assessing the effectiveness of FDCP in mitigating Doppler shift effects. Bit Error Rate (BER) results obtained through Regularized Sphere Decoding in diverse simulation scenarios affirm the capability of our proposed solution to effectively manage challenges, ensuring robust and high-quality connectivity in mobile communication networks.
