Performance of an adaptive data-rate MBC system using different FEC codings and ARQ protocols

The performance of meteor burst communication using adaptive data-rate modu lation is analysed. The transmitted data-rate is a function of the channel state, and is varied in a such way that the probability of bit error is kep t constant. Unlike other performance analyses, the message consists of data -packets, thus allowing more realistic ARQ protocols to be analysed. The pe rformance of the system is given in terms of average throughput, probabilit y of successful message completion in a given time span and average waiting time for different message lengths, with or without coding.
