Throughput efficiency of a class of continuous ARQ schemes under Markovian error patterns

The independent error model is often adopted to simplify the analysis of ARQ strategies. This assumption, however, is not true for channels where transmission errors occur in bursts. The limiting throughput efficiency of a class of continuous ARQ schemes with repeated transmissions is analysed under Markovian error patterns. The results show that the throughput efficiency can be significantly increased by transmitting multiple copies of each data block contiguously to the receiver. The results obtained are also compared under Markovian error patterns with those obtained under the independent error model.<>
