Abstract

Experimental and analytical results of applying Fritchman partitioned Markov chains to model the error sequences of mobile and stationary channels are obtained from real-time measurements. The Markov chain channel models were applied to the system using four modulation schemes, namely FSK, DPSK, QPSK and 8-ary PSK. Using error distributions obtained from both the experimental measurements and the channel models, BCH and Reed-Solomon error correcting codes of various block lengths and information rates are investigated. The effect of different interleaving depths on the block error rate is shown
