Due to the intense change of the transmission environment, the mobile communication system can not work in the optimal source coding rate and channel coding rate.
由于传输环境的剧烈变化，移动通信系统不能工作在最佳的信源编码速率和信道编码速率。
For the characteristics of wireless channel such as time-variety and high BER, the rate adjustable RCPT code is good for channel coding.
由于无线信道的时变、高误码等特性，码率可变的RCPT码是比较理想的信道编码方式。
Unequal error method is done. Rate compatible punctured convolutional code—RCPC is adopted as the channel coding to carry out the UEP.
本文采用了一种可生成多码率码的特殊的删余卷积码——RCPC码作为信道编码技术，以实现不等差错保护机制（UEP）。
