卡尔曼滤波，详细介绍了其具体过程，写论文必用,一定要收藏(It s very useful to write papers with Kalman filtering algorithms.)

matlab仿真qpsk在高斯信道和瑞利衰落信道下的误码率,做的还不错 (qpsk matlab simulation in AWGN channel and Rayleigh fading channel bit error rate, doing pretty good)

说明：  matlab实现最简单的DMC 预测控制 单入单出(The simplest DMC algorithm single in single out)

说明：  提取超声回波信号中回波时移的互相关计算。(Extraction echo ultrasonic echo signals of time-lapse cross-correlation calculation.)

说明：  关于Julia集和Mandelbrot集的MATLAB程序(the programs of Julia set and Mandelbrot set with MATLAB)

neural network _matlab(neural network)

说明：  该程序主要是仿真单极性码和双极性码在加性高斯白噪声信道中的理论误码率和实际误码率，并做一比较(The program is mainly simulation of single polar code and bipolar code theory in additive white gaussian noise channel bit error rate and the actual error rate, and make a comparison)

LDPC码的matlab实现，把解码的部分改过了，实验过很多次，符合理论要求，码长越长误码率越低(The implementation of LDPC code in MATLAB has changed the decoding part. It has been experimented many times and meets the theoretical requirements. The longer the code length, the lower the bit error rate.)

说明：  机床时频域信号特征提取，包括均方根值、峰值、峰值因子、峭度因子、脉冲因子、裕度系数、波形因子、功率谱密度、频率方差、均方频率(Eigenvalue extraction)

SAA7111和SAA7121的寄存器初始化官方配置，经过工程的考验(SAA7111 and SAA7121 official configuration register initialization, after the test engineering)
