Designing a bandpass and bandstop filter using matlab.

说明：  这是一篇关于多用户下行链路预编码的文章，主要是从一些基本的矩阵变换以及矩阵运算方面讲解一些原理，最后给出仿真实验

说明：  VC、Matlab混合编程使用范例，有助于轻松入门。(VC, Matlab use hybrid programming paradigm, help ease entry.)

悉尼大学SLAM团队的作品，可以与其SLAM算法程序配合，主要功能是进行数据的整理，将传感器采集的数据整理为易于分析的数据格式。(University of Sydney SLAM team work, you can SLAM algorithm with its main function is to carry out the collation of data, the sensor data collected for the easy analysis of data collation format.)

tpdsola algorithm,Synthesized speech can be produced by several different methods. All of these have some benefits and deficiencies that are discussed in this and previous chapters. The methods are usually classified into three groups: Articulatory synthesis, which attempts to model the human speech production system directly. Formant synthesis, which models the pole frequencies of speech signal or transfer function of vocal tract based on source-filter-model. Concatenative synthesis, which uses different length prerecorded samples derived from natural speech. The formant and concatenative methods are the most commonly used in present synthesis systems. The formant synthesis was dominant for long time, but today the concatenative method is becoming more and more popular. The articulatory method is still too complicated for high quality implementations, but may arise as a potential method in the future.
