ZigBee通信在传输系统中存在噪声干扰和多径衰落效应，造成系统误码率问题。采用信号相乘的直接序列扩频编码方法，增强ZigBee通信的抗干扰能力，建立了O-QPSK通信系统模式。通过对有DSSS O-QPSK和无DSSS O-QPSK通信的比较，得出有DSSS O-QPSK通信可以降低ZigBee通信的误码率，提高ZigBee通信的可靠性。通过Simulink仿真，仿真结果表明DSSS O-QPSK通信系统能够满足IEEE802.15.4协议的要求。
ZigBee communication exists noise interference and multipath fading effects in the transmission system, caused the system bit error rate problems. The paper uses signal multiplying direct sequence spread spectrum code method, enhanced ZigBee communication interference capability and established O-QPSK communication system mode. By comparing the DSSS O-QPSK and no DSSS O-QPSK, the DSSS O-QPSK communication can reduce the bit error rate and improve the reliability of ZigBee communications. By Simulink simulation, simulation results show that DSSS O-QPSK communication system can meet the requirements of IEEE802.15.4 agreement.
