Abstract

This paper compares the coded orthogonal frequency division multiplexing (COFDM) system and a single-carrier system using decision feedback equalization (DFE) in a Rayleigh-fading environment assuming perfect knowledge of the channel and ignoring error propagation in the DFE. Analytic techniques are introduced to bound the average probability of error of a single-carrier system using decision-feedback equalization and the average probability of error of a COFDM system in a two-path fading channel
