Error probability for block codes over channels with block interference

A methodology is presented to evaluate analytically the error probability for block codes over block interference channels. The proposed analysis is based on the knowledge of the moments of the bit-error probability over the interference, thus allowing, for instance, fast performance evaluation of block-coded slow frequency hopping (SFH) systems with antenna diversity over fading channels. As an example of application, slow frequency hopping multiple access (SFHMA) systems with nonideal interleaving are analyzed in the presence of fading, cochannel interference, and additive Gaussian noise.
