摘要

分析了蓝牙2.0+EDR新规范定义的3种调制方式在AWGN信道下的位错误率与平均接收信噪比的关系

推导了ACL分组的重传概率与平均接收信噪比的函数表达式。通过分组的重传概率与特性分析了ACL分组的传输性能

包括平均吞吐量、平均重传次数、平均传输时延等。提出了AWGN信道下的自适应分组选择策略

通过在不同的信噪比情况下选择合适的分组类型进行传输而获得最大吞吐量

给出了进行分组类型切换的信噪比门限值。分析结果与提出的策略适用于蓝牙数据传输性能的优化。

Abstract

Relations between bit error rate and average received signal-to-noise ratio （SNR） in AWGN channel were derived for three modulation modes defined by Bluetooth 2.0+EDR new specification. The function expressions of packet retransmission probability and average received SNR of ACL packets were put forward. The transmission performances of ACL packets

including average throughput

average retransmission times and average transmission delay

were investigated through the retransmission probabilities and characteristics of packets. The Adaptive packet selection strategy in AWGN channel was presented. The maximum throughput was obtained by selecting the appropriate packet types to transmit in different SNRs. The SNR threshold values for packet type switching were also presented. The analysis results and strategy presented adapt to optimizing Bluetooth data transmission performances.
