摘要
为对ZigBee技术在高密度节点分布情况下通信性能进行认识,设计了一套检测其通信性能的实验系统,该系统由单信道通信实验和四信道通信实验组成。为了验证ZigBee通信系统的最基本特性,在实验中不加入纠错或校验等措施,而是使用误码率这一参数对通信性能进行直观描述,系统通过对发送数据和接收数据的比较来检测单信道通信或四信道通信时的误码率。
An experiment system is designed to detect the communication performance of ZigBee so as to know the performance of ZigBee with high density of units. The system consists of the communication experiment of a channel and the communication experiment of four channels. Error correction or checkout is not used in the system so that we can get the basic characteristic of ZigBee system. Bit error is used in order to describe the communication performance directly. Bit error of communication in a single channel or many channels is detected by comparing the sending data with the receiving data.
