Abstract :
Efficient stop-and-wait, go-back-N and selective-repeat hybrid automatic-repeat-request (ARQ) protocols with adaptive forward error correction using punctured and repetition convolutional coding are proposed and analyzed. The basic idea is to vary the coding rate for error correction according to system parameters, such as the signal-to-noise ratio, the round trip delay and the buffer size at the receiver, so as to maximize the throughput efficiency. The authors refer to these schemes as adaptive coding rate (ACR) ARQ protocols. The performance of the proposed ACR ARQ protocols is evaluated for an additive white Gaussian noise channel
