Effectiveness evaluation of coded FTN signaling in the presence of nonlinear distortion under multipath fading channels

Abstract

This study investigates the transmission performance of coded faster-than-Nyquist (FTN) signaling based on single-carrier with frequency-domain equalization in the presence of nonlinear distortion and multipath fading. In our performance evaluation, the effects of nonlinear distortion and channel coding were determined using a power amplifier model based on the Rapp model and turbo coding, respectively, which were incorporated into the frame error rate and throughput performance of FTN signaling. Moreover, we compared the performance of coded FTN and coded orthogonal frequency division multiplexing under the same transmission rate using computer simulations to verify the effectiveness of FTN signaling under nonlinear distortion and frequency selective fading.
