摘要
本文给出了一种自适应信道编码技术,它能够跟踪信道状态的长时变化特性,自动调节信道编码效率和相应的信源编码速率,使实际信息率与信道状态保持匹配,从而大大提高时变信道上的传输效率。这种方案已经在实际中得到了应用,并取得了良好的效果。
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.
