鲁棒自适应滤波器的MATLAB仿真和实现。这里采用的一种变步长的NLMS算法（VSSNLMS）(Robust adaptive filter MATLAB simulation and implementation. A variable-step NLMS algorithm (VSSNLMS) used here)

可以降维分析，还有bp神经网络，非常方便学习。大家可以随意下载，(Dimensionality reduction analysis)

级联积分－梳状(Cascaded Integrator–Comb，CIC)滤波器，是种高 效滤波器。它是一种线形相位FIR滤波器，由工作在高抽样率的级联理 想积分器和低抽样率的级联微分器组成,根据抗混叠和抗镜像的指标 确定所需的级联数目。 (Cascaded integrator- comb (Cascaded Integrator-Comb, CIC) filter, is the kind of high efficiency filter. It is a linear phase FIR filter, high sampling rate by the work in the cascade of an ideal integrator and a low sampling rate of the cascade differentiator formed, according to anti-aliasing and anti-mirror of the indicators to determine the number of required cascade.)

自己写的几个小程序，包括冲激函数，阶跃函数，时域采样，恢复，内插等程序。很好用。(Write several small programs, including the impulse function, step function, time domain sampling, recovery, interpolation procedures. Good use.)

Orthogonal Frequency Division Multiplexing with Index Modulation,is proposed for operation over frequency-selective and rapidly time-varying fading channels

OFDM信道估计，该文件夹包括19个M文件，包括误码率检测，插值计算，瑞利信道等(OFDM channel estimation, the folder includes 19 M files, including bit error rate detection, interpolation, Rayleigh channel, etc.)

通信系统中用于设别调制方式的5个特征参数的提取(Communication Systems for the set up of other modulation characteristics of the five parameters extracted)
