Some ARQ protocols with finite receiver buffer

摘要

Some new schemes for communication systems using error-detecting codes are described. These schemes use hybrid strategies for the retransmission of the codewords detected in error, and combine the advantages of the go-back-N and selective protocols. The memory, introduced at the receiver side, enhances their performance with respect to the classical schemes. The results show that the protocols described provide a net improvement with respect to other similar schemes.
