摘要
由于无线信道的时变、高误码等特性,要求信道编码方式有较强的抗误码能力,而且能够自适应无线信道状态的变化。码率匹配删余Turbo码(RCPT)能实现这样的编码要求,并且能提供适应不同需要的不等差错保护(UEP)。介绍了RCPT码在移动通信中的应用,讨论了新的自适应编码调制及不等差错保护方案。
The characteristics of wireless channel such as time - variety and high BER require not only strong error correcting capability of channel coding method but also the ability to adjust bit rate according to the state of wireless channel. The RCPT codes can fulfill such requirement and protect the date unequally according to the different requests. The application of RCPT over the mobile communication channel is introduced, and new schemes about adaptive coding system and unequal error protection are discussed.
