Adaptive Packet Selection Strategy for Broadcast Performance of Bluetooth Improvement
Fei Xu, Yiqi Zhuang, Guo Sheng Feng · Jisuanji gongcheng · 2007
Relations between bit error rate(BER) and average received signal-to-noise ratio(SNR) in AWGN channel are derived for π/4-DQPSK and 8DPSK modulations modes in Bluetooth 2.0+EDR specification.Function expressions of packet broadcasting retransmission probability and average received SNR of ACL data packets are put forward.The adaptive packet selection policy is presented for the Bluetooth 2.0+EDR specification packets in different SNRs,which selects proper packet in different SNRs to get the least retransmission times and the maximal broadcasting throughput.Simulation results can be used to achieve a good broadcast performance in different channel conditions.
