在MATLAB上设计一个（2，1，3）卷积编码器和对应的采用维特比译码算法的译码器。编码器的生成多项式为：[1 0 1；1 1 1]。将编码器的输出经过一个高斯白噪声信道的结果作为译码器的输入，观察比较译码器输出和编码器输入，了解卷积码的容错性，并计算译码结果的误比特率.(A convolutional coder (2, 1, 3) and corresponding decoder using Vitby decoding algorithm are designed on MATLAB. The generating polynomial of encoder is: [1 01; 11 1]. The output of the encoder through a Gauss white noise channel as a result of the decoder input, compare the output of the decoder and encoder input, understand the fault tolerance of convolutional code, and calculate the decoding results of bit error rate.)

语音编码方案的选取对移动通信系统的通话质量、信道容量等有重要影响。本文讨论了TD-SCDMA系统中AMR语音编码的自适应机制，同时分析了AMR中代数码本线性预测(ACELP)算法及实现过程。该方案可以在一块TMS320C5510上实现。(The selection of voice coding schemes for mobile communication systems the quality of the call, such as channel capacity have had a significant impact. In this paper, TD-SCDMA System AMR Adaptive speech coding mechanism, at the same time analysis of AMR in the generation of Digital Linear Prediction (ACELP) algorithm and the realization of the process. The program can be achieved in a TMS320C5510.)
