摘　　要：为了进一步改进蓝牙在通用频段的干扰问题,利用蓝牙系统跳频序列的改进算法实现了误码率的明显降低。通过算法的系统仿真及性能分析得到:新算法系统的抗变频干扰性能要远远强于原系统,可以抵抗大多数的干扰,平均误码率只有0.002 900;与原系统相比,变频干扰下其误码率有了约55.4%的下降幅度,随机频率干扰下的误码率也降低了50%以上。To further improve the Bluetooth interference problems in common band, Bluetooth system frequency hopping sequence improved algorithm is implemented to significantly reduce error rate. System simulation and performance analysis can obtain： anti-interference performance of the new algo- rithm system frequency is much stronger than the original system that can resist most of the interference, and the average error rate of only O. 002 900. Compared with the original system, interfere with the down-conversion error rate is approximately down 55.4%, and the error rate of random frequency interference is also reduced more than 50%.
