Bound estimation for coded faster‐than‐Nyquist system

Abstract

Frame error rate bound is a useful tool to predict the performance behaviour of coded faster than Nyquist system (FTN). In this Letter, the Euclidean distance distribution (EDD) of FTN signalling is assumed continuous and obeys the Gaussian distribution for its long memory length. By using the autocorrelation properties of the error sequences, the EDD of FTN is estimated and the simplified bound is further derived which indicates that the performance of coded FTN system is bounded by the performance of employed coding scheme. Simulation results show that the bound is well matched with the simulated performance in high SNR regime.
