求一个40阶的雷米兹带通滤波器，并绘出两个滤波器的幅频特性图(Remez seeking a 40-order band-pass filter, and plot the frequency characteristics of two filters map)

信号叠加单频噪声，并利用SMI算法在16个天线阵元数条件下计算阵列方向图(Superposition of single frequency noise signal, and the SMI algorithm using 16 antenna elements in a number of conditions calculated array pattern)

利用M函数仿真扩频通信系统。6个用户的CDMA的同步通信系统，每个用户利用L＝31的Gold码，进行扩频，信道为AWGN信道，接收端利用匹配滤波器进行检测。绘出当N＝10000个发射比特下，SNR＝0：15（dB）时的误码率曲线。 (M function simulation using Spread Spectrum Communication System. 6 simultaneous users of CDMA communication system, each user of the L = 31 the use of Gold codes for spread spectrum, channel for the AWGN channel, the receiving end to detect the use of matched filter. Drawn when N = 10000 bits of transmission, SNR = 0:15 (dB) when the bit error rate curve.)

自己编写的基本的二进制GA程序，均匀交叉，单点变异(It is the cold of simple binary GA)

采用L-D算法，估算自回归模型（AR模型）系数。L-D法是一种矩阵递推估计法(LD algorithm to estimate the coefficients of the autoregressive model (AR model). The LD method is a matrix recursive estimation method)

matlab实现图像直方图均衡化 不需要调用函数(Matlab image histogram equalization Don t need to call a function )

地面站授权控制，通过DTU控制盒来实现对地面站，飞控和服务器进行信号控制与处理。(The ground station authorization control, through the DTU control box to realize to the ground station, flight control and server control and signal processing.)

在诸多ICA算法中，固定点算法 (也称FastlCA)以其收敛速度快、分离效果好被广泛应用于信号处理领域。该算法能很好地从观测信号中估计出相互统计独立的、被未知因素混合的原始信号。(In many ICA algorithms, fixed-point algorithm (also known as FastlCA) for its fast convergence and good separation effect is widely used signal processing. The algorithm can estimate from the observed signals statistically independent each other, unknown factors are a mixture of the original signal.)

this is a face detection code .With high efficiency and accuracy
