Abstract

The transmission delay and throughput performances of a hybrid Go‐Back‐N automatic repeat request (ARQ) scheme are analyzed. In the hybrid scheme, multiple alternate transmissions of the copy and parity block of each data block are repeated continuously by transmitter. The receiver detects or corrects errors in a received block by using Wang and Lin's error control algorithm. It is shown that we can obtain the optimum total number of continuous transmissions of copies and parity blocks, which minimizes the average delay time and maximizes the throughput.
