matlab的 通信 系统仿真，希望对大家又帮助(Matlab communications system simulation, we also hope to help)

用来求解非线性系统周期解的打靶法，程序简单易学。(The shooting method is used to solve the nonlinear system, periodic solution, the program easy to learn.)

基于递归最小二乘算法的自适应数字波束形成器程序(Recursive least squares algorithm based on adaptive digital beamformer program)

信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signals are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. It is the sampling frequency. Respectively Levinson recursion method and Burg method for power spectrum estimation, and change the length of the data analysis, the impact of model order estimation result spectrum.)
