Abstract

In the last decade the growth of wireless communication has been rapid. One critical issue in wireless systems is the efficient encoding of data to ensure correctness in the presence of noise and multipath fading. We propose some encoding schemes which span the FEC/ARQ spectrum and analyze them with respect to throughput and delay. We conclude with an adaptive algorithm for choosing the optimal encoding scheme based on observed error rates
