Abstract

Using the probabilistic models for meteor burst channel parameters, expressions are derived for performance characteristics of an automatic-repeat-request (ARQ) communications system. Performance measures such as throughput rate, waiting time to receive a message correctly, and probability of successful message delivery within some specified time are functions of packet size and transmission data rate. It is shown that a hybrid FEC-ARQ (forward-error-correction-ARQ) strategy yields higher throughput, lower waiting time, and increased probability of correct packet reception, as compared to uncoded transmission, but only when the code rate approaches 1. The coding employed was rate 1/n and rate k/nconvolutional
