摘要
介绍了TETRA通信系统中语音信道的编解码方案,使用率适应删除卷积码有效地减少了码元的个数,并对该方案在DSP开发环境CCS上进行了仿真。这种短小、高效的信道编码方案可用于对讲机和通信设备。
The channel encoding scheme for speech in TETRA is introduced. By using rate compatible punctured convolution code, the quantity of the code element can be deduced effectively. The scheme is simulated on CCS. Such smallish, high effective channel encode scheme can be used in interphone and other communication devices.
