【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。更多还原

【Abstract】 This paper proposes an adaptive channel coding strategy, which chooses different FEC code dynamically according to feed-back information of the current state of the channel, so that acquires both high efficiency as well as excellent error-correcting perfor-mance. This method has been implemented in shortwave communication, and gets good gains.更多还原
