摘要
介绍纠错编码原理,着重介绍几种纠错编码例如线性分组码、卷积码、级联码,同时介绍无线网络传输的特点,无线传输中误码产生的主要原因。结合这两点,介绍在无线局域网中采用的纠错编码方式,编码纠正错误对于帧错误概率和吞吐都有改善作用,在特定的误码率条件下吞吐量有显著的提高。
Introduces the error correction coding,and emphatically introduces several principles such as linear error code block codes,convolution code,cascade yards,and introduces the characteristics of the wireless network transmission,frequency wireless transmission error.And combined these two,introduces the error control coding methods used in the wireless LAN,and the coding correction error will help to improve the correcting errors probability and stimulation frames,and at certain BER conditions throughput will improve significantly.
