Abstract

The bit error rate (BER) performance analysis of maximum-likelihood (ML) based decode and forward (DF) cooperative diversity systems has been a subject of consid- erable interest. Exact analysis of ML-DF transmission has been considered a chal- lenging problem due to the nonlinear characteristic of the ML detector. In this thesis, we provide exact expressions for the BER of ML-DF cooperative systems employing a single relay. This is done by using a novel theory of conditionally Gaussian random variables and special hypergeometric functions. By expressing the ML decision vari- able in terms of functions of conditionally Gaussian variables, exact expressions for the BER of the ML-DF system are obtained. Through simulation results, we verify the validity of the derived analytical expressions.
