基于MATLAB的四自由度机械臂运动学仿真研究

QPSK误码率仿真程序，给出了比较可行，准确的方法(QPSK BER simulation program are given more feasible and accurate method)

说明：  本文主要是通过Buck变换器推导出移相全桥变换器的小信号电路模型，接着用MATLAB软件进行仿 真，来判断系统的稳定性。 ( This paper is mainly through the Buck converter is deduced the whole bridge converter phase shifting small signal circuit model, then the MATLAB software to copy True, to judge the stability of the system.)

Frequency-domain identification toolbox

HIBRENATE SHARD开发文档,是官方文档的翻译后的成果(HIBRENATE SHARD development docs)

使用matlab编写的仿真带多普勒频移的单信道模型(Prepared using the matlab simulation with Doppler shift of the single-channel model)

reddy snr estimator. run the interleaver file first than run the estimator file and get the results.

说明：  使用matlab 实现的多相滤波。。。。。(With the realization of Mmatlab multiphase filtering )

噪声环境下的予以增强程序，用小波函数 db6 对信号进行3层分解(Noise environment to be enhanced procedures DB6 wavelet function with the signal 3-layer decomposition)
