自適應(yīng)信道編碼技術(shù)在短波數(shù)字通信中的應(yīng)用

本文給出了一種自適應(yīng)信道編碼技術(shù)，它能夠跟蹤信道狀態(tài)的長時變化特性，自動調(diào)
節(jié)信道編碼效率和相應(yīng)的信源編碼速率，使實際信息率與信道狀態(tài)保持匹配，從而大大提高時變信道上的傳輸效率。這種方案已經(jīng)在實際中得到了應(yīng)用，并取得了良好的效果。

Implementation of an adaptive channel coding strategy in shortwave communication Lin Yi-qing, CUI Hui-jun, TANG Kun (Department of Electronic Engineering, Tsinghua University, Beijing, 100084, China) Abstract: This paper proposes an adaptive channel coding strategy, which chooses different FEC code dynamically according to feedback information of the current state of the channel, so that acquires both high efficiency as well as excellent error-correcting performance. This method has been implemented in shortwave communication, and gets good gains.
Keywords: adaptive channel coding; RCPC; shortwave communication
