Abstract :
In this paper we suggest and compare the performance of different systems that can be used for wireless asynchronous transfer mode (WATM) to improve performance in terms of cell loss ratio and throughput under a certain fading wireless channel for a certain period of time. The type of fading considered in this paper is a result of a sudden and a sharp change in the signal level due to a sudden change in the weather condition (e.g. lightning) or due to a multipath effect caused by a mobile obstacle. It was found that compressing the ATM cell header and then applying the Bose-Chaudhuri-Hocquenghem BCH (i+18,i,3) code to the compressed header during the fading period, when the bit error rate ranges between 10-3 and 10-1, results in an optimum performance in terms of cell loss ratio and throughput
