LU Tian-ran · 2009
The Bluetooth piconet needs better average channel SNR(received signal-to-noise ratio) in order to transmit data effectively in different channels with the modulation methods in Bluetooth specification.The MSK modulation method could improve the data throughput performance of wireless communication in noisy environment efficiently.The Bluetooth data packet transmission mathematical model was built;the relations of Bluetooth piconet data throughput and the average channel SNR were derived.The corresponding functions were deduced.The data transmission perfor-mance with the MSK method and modulation methods in Bluetooth specification was analyzed.The MSK modulation method can improve the Bluetooth piconet data transmission throughput in low SNR environment.The simulation result proved the conclusion.
