摘　　要：针对无线传感器网络节点间的信道数据传输,研究了传感器采集数据的发送、处理和接收过程,进行信号的有效传递,并实现无线网络对特定区域的监测.设计中的传输信道编码采用BCH码编译,以时域迭代算法结构校检编码,自动地纠正传输中的错误信息,并达到信道编码较低的误码率,实现了网络节点间数据的有效传输.In order to complete the data channel transmission between wireless sensor network nodes,it is researched how to send,process and receive data that a sensor has detected.With effective signal transferring,wireless sensor network nodes can detect some designated locations.This paper introduces a transmission channel code which is designed with BCH code encoding and decoding.Coding is checked with time domain iterative algorithm structure.Error messages can be corrected automatically.Simultaneously,the lower bit error is achieved.The effective transmission of the network nodes data can be realized.
