利用FFT捕获PN码，并计算不同信噪比下的检测概率。(Capture PN code with FFT, and calculate the probability of detection under different signal to noise ratio.)

Bit error rate performance of BPSK over Rayleigh fading wireless channel and its comparison with ber of BPSK transmission over AWGN channel.

粒子滤波matlab工具箱，用于学习粒子滤波(particle filter matlab toolbox,it s helpful to study particle filtering.)

说明：  利用多尺度小波分解侦测时间序列中奇异点位置(multiscale wavelet decomposition time sequence detection singular position)

精通matlab c语言编程，对于学习matlab的学习和c语言的学习都很有好处。可以帮助初学者掌握较好的编程技能(Proficient in matlab c language programming, learning for learning matlab and c language learning is very good. Can help beginners grasp the good programming skills)

Design a linear phase minimum order FIR Band Stop filter to stop the frequency band 0.45π to 0.55π with atleast 60dB attenuation at the edges. Further -3dB frequencies are required to be at 0.3π and 0.7π. 1. Plot the frequency response of the psuedo magnitude function using (a)rectangular window, (b)Hann window and (c) Hamming window. 2. Plot the frequency response for Rectangular and Hamming window for a length of 1024 to demonstrate the fact that the increase in the length, doesn t reduce undershoot and overshoot in Rectangular window.

Matlab中所有的内部函数，学习后能够全览matlab中的函数。(Matlab, all internal functions, learning later to be fully in relation to the function of matlab.)

说明：  matlab中不同序列的分类，利用内积不同来分类，附注释(matlab different sequence classification, the use of inner product different to the classification of annotated)

这是解三对角线性方程组的一种方法。能有效的快速求解。(This was three diagonal equations of a method. Fast effective solution.)

MATLAB，即“矩阵实验室”，它是以矩阵为基本运算单元。因此，从最基本的运算单元出发，介绍MATLAB的命令及其用法3。(MATLAB, "Matrix lab," It was based on the matrix of the basic computing unit. Therefore, from the most basic computing element is introduced, and MATLAB ordered three of its use.)
