本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

SVM的多分类问题MATLAB工具包。传统的SVM只支持二分类问题，MATLAB自带的工具包也存在同样的问题。可以在setpath中导入此包，便可轻松将SVM问题扩展到多分类的层面。(A matlab toolkit to solving multi-classification problems based on svm. Traditional svm and the matlab toolkit svmtrain can only support for bi-classification problems which could hardly satisfy users requirments. U can import this toolkit by click setpath and can easily do what you like.)
