Performance analysis of non-interleaved concatenated codes on time-correlated fading channels

Abstract

We present an analytical method for evaluating the performance of non-interleaved concatenated codes over channels modeled as a non-frequency-selective, time-correlated Rician fading channel with a known power spectral density. The main idea is to model the communication system from the modulator input to the demodulator output as a binary finite state channel (FSC) model, and apply powerful enumeration techniques to such a discrete channel in order to gain useful information on system performance. The concatenated scheme makes use of two codes: Reed Solomon (RS) codes are employed for the outer code, and binary block codes are used as the inner code. This is an interesting alternative approach with respect to computer simulations.
