Fan Yang, Ke Wang, Zhihong Qian · Jisuanji gongcheng · 2006
Relations between bit error rate and average received signal-to-noise ratio(SNR) in AWGN channel are derived for GFSK,π/4-DQPSK and 8DPSK modulation modes defined by Bluetooth EDR specification.The function expressions of packet retransmission probability and average received SNR of new ACL data packets are put forward.The transmission performance,including average throughput,average retransmission times and average transmission delay,of all data packets in different SNRs are investigated through the packet retransmission probability and different characteristics of packets.It’s the first time to research the newly adopted modulations and packet transmission performances of Bluetooth EDR specification,the analysis results contained can be sever as a theoretic benchmark against other researches.
