Abstract
A digital mobile communication system, with a flat-flat fading channel model is studied. Block encoding and modulation along with maximum likelihood block correlation demodulation is considered. It is shown that for memory modulation schemes, interleaving can not be used if a soft decision maximum likelihood block correlation receiver is being used. The union bound expressions for the probability of channel code word error are derived for various modulation schemes. Simple sequential algorithms are presented to calculate the error probability for different modulation schemes and the performance of (3, 1) repetition code, (7, 4) Hamming code and (15, 5), (31, 6) BCH codes has been evaluated.
