摘要
ZigBee是一种低功耗、低成本的短距离无线通信技术。针对ZigBee无线通信系统进行了研究,通过比较扩频通信系统和不扩频通信系统,可知扩频通信能够减小误比特率,提高系统的可靠性。通过matlab仿真,仿真结果表明经过扩频的通信系统达到了IEEE802.15.4协议的要求。
ZigBee is a kind of short wireless communication technology. ZigBee for wireless communication systems have been studied. By comparing the spread spectrum communications or none spread spectrum communications, we know that the spread spectrum communications can reduce the error of bit rate, and improve system reliability. The Matlab simulation results show that the spread spectrum communication system meets the requirement of the IEEE 802.15.4 standard.
