hdb3 AMI 码 这是自个儿用matlab编的关于HDB3，AMI的仿真 (hdb3 AMI)

时频分析工具包，可用于非平稳信号处理，for matlab(This is the Time-Frequency Toolbox, a collection of about 100 M-files , developed for the analysis of non-stationary signals using time-frequency distributions. It consists in groups of signal generation files, processing files and post-processing files (including visualization tools). The toolbox contains numerous algorithms for time-frequency signal analysis, with special emphasis on quadratic energy distributions within Cohen s class and the affine class, including most recent developments based on reassignment. The Time-Frequency Toolbox has been developed by Francois Auger, Olivier Lemoine, Paulo Gonlv and Patrick Flandrin during the years 1995-1996. Later, modifications for Matlab 5 were made available.)

本程序设计了一个最佳升余弦滚降系统，包括输入输出信号的波形、功率谱、眼图和系统误码率曲线(This procedure is designed or one of the best cosine roll-off system, including input and output signal waveform, power spectrum, eye diagram and BER curves)

说明：  永磁同步电机输出特性模拟程序。此处电机材料为线性。(Permanent magnet synchronous motor output characteristics simulation program. Material here for the linear motor.)

Jacobi迭代求线性方程组，对初学编程的同学很有帮助的(Jacobi iterative linear equations, students of the beginner program helpful)

内有关于监护仪的相关设计，仅供参考，不太完善请见谅(There on the monitor related design, for reference only, not perfect, please forgive me)

选取滤波器（低通滤波器和带阻滤波器）采样点之间信号并与对应的输入信号进行比较的源程序。 (Select filter (low-pass filter and band stop filter) the signal between sampling points and the corresponding input signal for comparison of the source.)

有关天线方向图的实现，主要是线阵方向图的实现(The implementation of the antenna pattern, mainly linear array)

Histogram of letters and pair of letters from a text file.

模拟信号在多天线下传输的整个过程，包括调制、过信道、解调、计算误码率等(The analog signal in a multiple antenna transmission the entire process, including modulation, over a channel demodulation, calculate the error rate)
