A new selective retransmitted ARQ system

A partly repeated ARQ error control system of combining continuous transmission pattern with stop-and-wait (SW) ARQ pattern is considered. The system transmits data by means of a half-duplex channel. It can save the frequency-band or channel requirements compared with the GBN ARQ strategy, while its throughput is much higher than that of SW ARQ strategy and approximates to the throughput of the GBN ARQ strategy. An analysis shows that the system has excellent performance and and is of practical value.<
