中文摘要：
比较了蓝牙协议各个版本对其数据传输性能的影响,分类讨论了分组选择算法、重传机制、数据传输的干扰及安全等。针对目前存在的问题,提出了引入扩展戈莱编码和最小频移键控（MSK）调制的数据分组改进方案,提高了系统的抗干扰性和吞吐量,并提出了基于信道转换与MSK调制的同频干扰抑制方法,使皮可网的载干比和吞吐量有明显改善,最后总结并对未来工作提出设想和展望。
英文摘要：
The different impact assessments on performance of data transmission of multiple Bluetooth protocol versions were analyzed.Packet selection algorithms,retransmission mechanisms,interference and security were discussed respec-tively.Strategies,employing extended-golay code and minimum frequency shift keying（MSK） modulation were pro-posed,which enhanced the probability of anti-interference and throughput of data packet.Moreover,a co-channel inter-ference suppression approach based on channel switching and MSK modulation was proposed,which improved the car-rier to interference ratio and throughput in piconets.Finally,the work was summarized and expectations as well as pre-meditation of the future were presented.
