Pulse Code Modulation (PCM)

仿真4-PAM（脉冲幅度调制）载波调制信号在AWGN（加性高斯白噪声AWGN(Additive White Gaussian Noise)）信道下的误码率和误比特率性能，并与理论值相比较。(Simulation 4-PAM (pulse amplitude modulation) modulation signal in AWGN (additive white Gaussian noise AWGN (Additive White Gaussian Noise)) under the channel bit error rate and bit error rate performance, and compared with the theoretical value.)

完整的二维非线性共轭梯度反演源代码，作者是Mackie 和Rodi。(Complete two-dimensional nonlinear conjugate gradient inversion source code, the author is Mackie and Rodi.)

生成一元分布随机数、蒙特卡洛方法；正态总体参数的检验；描述性统计量等(Generating a bivariate distribution, random numbers, Monte Carlo methods, testing of normal population parameters, descriptive statistics, etc.)

分数阶Fourier变换，直接根据公式实现，没有用快速算法(Fractional Fourier transform, directly under the formula to achieve, not with the fast algorithm)

信号与系统实验(高级) 实验六 电话拨号音的合成与识别(Signals and Systems Experiment (advanced) experiments six telephone dial tone Synthesis and Recognition)

说明：  通过利用Weichselberger模型产生瑞利衰落信道(rayleigh)

simulink学习教材，快速学会simulink的基本使用(Simulink learning materials, basic use quickly learn to simulink)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)
