IIR 数字滤波器的设计与实现
说明： 设计一个巴特沃兹数字低通滤波器，其技术指标为：3dB带宽为0.2π，阻带截止频率为0.3π，通带纹波为1dB，阻带衰减大于30dB，采样间隔T=10ms。
1）采用冲激响应不变法；
2）采用双线性变换法设计；
3）采用FIR的窗函数（Hanning窗、Hamming窗或Blackman窗）设计。(A Butterworth digital low-pass filter is designed. Its technical specifications are: 3 dB bandwidth is 0.2 pi, stopband cut-off frequency is 0.3 pi, passband ripple is 1 dB, stopband attenuation is more than 30 dB, sampling interval T=10 Ms. 1) Impulse response invariance method is adopted. 2) Design by bilinear transformation method; 3) FIR window function (Hanning window, Hamming window or Blackman window) is used to design.)

serial to parallel
直接序列扩频通信中采用QPSK调制时，须将产生的串行数据首先串并变换成两路，本程序就是实现这种串并变换！(Direct sequence spread spectrum communications using QPSK modulation, it is necessary to have a string of serial data and converted into the first two, the process is to realize such a string, and transform!)

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.)
