模拟OFDM体制的数字电视信号DVB-T的接收全过程，包括下变频、D/A转换、滤波、星座解调等。。。很实用！(Simulated OFDM system, DVB-T digital TV signal reception of the entire process, including down-conversion, D/A conversion, filtering, demodulation and other constellations. . . It works!)

国外高校老师编写的语音信号特征提取程序，非常实用初学者研究( [E, V, A, P] = analysis(x, N, U, M) extracts vocoder parameters E, V, A, and P from the speech signal x on a frame by frame basis. N is the analysis frame length, U is the update length, and M is the order of the linear prediction analysis. The return arguments are the extracted parameters, where E, V, and P are vectors with "n_frames" (the number of analysis frames, see code below) elements, A is a (n_frames, M+1) size matrix (includes the leading 1 of the polynomial).)

首先扼要地阐述矩量法分析天线的一般概念和基本思想，然后分别采用几种不同的积 分方程对线天线进行矩量法分析，并与解析计算结果进行比较，两者的一致性说明了计算结果的正确性。(First, a brief moment method analysis of antennas described the general concepts and basic ideas, and then were used for several different line of antenna integral equation moment method analysis, and results were compared with the analytical calculation, the consistency between the description of the calculation accuracy of the results.)
