Abstract

Bluetooth is a universal short-range radio link for high-speed wireless communications. One critical issue in wireless communication systems is the efficient encoding of data to ensure correctness in the presence of noise and multipath fading. Bluetooth provides two techniques to handle link-level transmission errors: automatic repeat request (ARQ) and forward error correction (FEC). We propose an adaptive hybrid ARQ/FEC scheme to enhance the data throughput over Bluetooth based on observed error rates. Simulation results show that the adaptive ARQ/FEC coding scheme significantly improves the data performance of Bluetooth wireless communication systems compared to stationary ARQ/FEC schemes which do not take the channel conditions into account
