Parzen-window-method
此为模式识别中Parzen窗法估计概率密度函数。
全部程序流程如下:
1、读取FAMALE.TXT文件把身高或体重给数组,并求x1的样本数N1和窗宽、体宽;
2、读取MALE.TXT文件把身高或体重给数组,并求x2的样本数N2和窗宽、体宽;
3、读取Test2.txt文件把对应的身高或体重给数组A并求A的样本数M;
4、利用Parzen窗法估计概率密度函数判别男女性别;
5、对本判别的错误率进行统计。
(This is the pattern recognition Parzen window method to estimate the probability density function .
All program flow is as follows :
1 , read FAMALE.TXT file to height or weight to the array, and find the number of samples x1 N1 and window width , body width
2 , read MALE.TXT file to height or weight to the array, and find the number of samples x2 N2 and window width , body width
3 , read Test2.txt file to the corresponding height or weight requirements for the array A and A is the number of samples M
4 , the use of Parzen window method to estimate the probability density function of gender discrimination
5 , determine the error rate of the statistics .

GoldsequenceCDMAsimulation
写一个MATLAB程序,实现4个时间同步的CDMA用户的仿真,其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制(+-1)调制。每个用户的接收端将这个复合的CDMA接收信号相关,而这个复合的信号都在它们各自的序列上受到AWGN的污损(基于按码片相加)。在N=10000信息比特下,仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)
