Throughput performance of some continuous ARQ schemes with memory

A class of continuous ARQ schemes with memory, where multiple copies of each data block are sent contiguously instead of one single copy, and several copies of the same data block are combined to make a decision at the receiver, is considered. The throughput efficiency analysis is carried out based on the model proposed by Bruneel. Results show that the performance of the investigated ARQ schemes can be considerably improved if the receiver has some memory.
