Abstract :
The probability of instantaneous accepted packet error outage (IAPEO) is proposed as a performance measure for packet transmission with automatic-repeat-request (ARQ) schemes over wireless channels. It is defined as the probability that the instantaneous accepted packet error probability (IAPEP) exceeds an IAPEP threshold. We obtain a closed-form upper bound expression for IAPEO of a pure ARQ over Rayleigh fading, and observe that, in order to satisfy a system design requirement of maximum tolerable IAPEO, the system must operate above a minimum SNR value. We next propose an ARQ scheme by incorporating channel gain monitoring (ARQCGM), such that the IAPEO requirement can be satisfied at any SNR value with the right channel gain threshold. The IAPEO performance of ARQ-CGM with selective repeat retransmission protocol is related to the conventional performance measures, i.e. average accepted packet error probability, throughput and goodput.
