Abstract :
An enhanced version of the space-alternating generalised expectation-maximisation (SAGE) algorithm based on distributed-source modelling is proposed. This new algorithm shows an improved performance compared to that of the classical SAGE algorithm when applied to a distributed-source environment, especially when the successive interference cancellation (SIC) technique is employed within the SAGE algorithm.
