Abstract :
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.
