不适用matlab自带滤波器函数的fir低通滤波器设计( low-pass filter )

This m file performs the QPSK transmission and reception.

模拟噪声的程序，可以根据需要改写，主要功能是实现噪声模型 (Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details: op_channel = additivenoise(input_signal) mathematical Model: s(t) input signal to channel (=sig_ip) n(t)additive random noise process added by channel (=noise_mat) a(t) attenutation factor , here it is taken as random(=att_fact) out put signal r(t) = a .* s(t)+ n(t) an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal )

用于在matlab环境下进行自适应滤波与卡尔曼滤波的仿真分析的实例(Under the matlab environment for adaptive filter and Kalman filter simulation examples)

可以用此代码信号实现频谱仿真，希望对大家有用(You can use this code to achieve spectrum signal simulation, we hope to be useful)

pb的小例子,是PB中的游标的经品,实现查询功能.(pb small examples, PB cursor on the goods and realize the inquiry.)

说明：  用动量梯度下降法训练BP网络 已知输入向量为P=[-1,-2,3,1 -1,1,5,3]，目标输出为T=[-1,-1,1,1]。 (Gradient descent with momentum BP network training input vector is known as P = [-1,-2,3,1 -1,1,5,3], the target output for the T = [-1,-1,1, 1].)

此程序用提升法实现第二代小波变换，分析对象是wbarb(Use this procedure to upgrade laws to achieve the second-generation wavelet transform, the analysis is wbarb)

不调用MATLAB本身的神经网络工具箱实现两层神经网络(creat a simple two layers ANN without using the ANN toolbox of MATLAB )

MATLAB code for all of the examples in the text is supplied with the CompEcon Toolbox
