ARQ With Packet-Error-Outage-Probability QoS Measure

Free registration required

Executive Summary

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 conditioned on a given channel gain exceeds a threshold. The authors obtain a closed-form upper bound on the 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.
