Performance of coded multistage detection in correlated Rayleigh channels

In this paper, we estimate the performance of coded multistage detectors operating over a correlated Rayleigh fading channel without interleaving. We derive analytical estimates for the single-cell capacity of such systems by estimating the effective signal-to-noise ratio (SNR) after each stage and by calculating the exact symbol error probabilities of the channel decoder in a correlated Rayleigh fading channel. These analytical estimates are compared with the capacity estimates archived through simulations.
