| Abstract: | 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. |
