FRAME ERROR RATE EVALUATION OF A C-ARQ PROTOCOL WITH MAXIMUM-LIKELIHOOD FRAME COMBINING

摘要

In this paper a Cooperative-ARQ (C-ARQ) with a maximum-likelihood frame combiner (ML-FC) protocol is studied. C-ARQ is well suited for wireless transmission in either infrastructure or ad-hoc networks, as it exploits some of the unique characteristics of wireless media, such as the natural broadcast of wireless transmission and receiver diversity. The frame combiner can help in the case in which any received frame is correct, exploiting the same characteristics of wireless transmission but at a bit level. The paper studies the Frame Error Rate for this kind of system, showing that significant improvements can be obtained.
