台湾人写的用matlab读写语音文件的ppt.介绍相当好,适合语音处理的入门文档(Written by Taiwan to use matlab to read and write audio file ppt. Introduce a very good deal for voice entry document)

spectrum sensing for cognitive radio using energy detection

坐标变换，比较实用，程序完整，调试成功，可直接运行(shift_axis_to_origin2)

对数据进行reof处理，得到数据的空间模态和时间系数(Matlab function of reof)

This code use a Differential Evolution optimization algorithm. and then optimize the learning rates of neural network. used is JENKIN s gasro and makey dataset.

BPSK仿真，Eb/N0=0:10,得出BER与Eb/N0的关系曲线，AWGN信道(BPSK simulation, Eb/N0 = 0:10, draw BER versus Eb/N0 of the curve, AWGN channel)

衰落是由于发射机与接收机之间空间位置的微小变化引起的，描述小范围内接收信号场强中瞬时值的快速变化特性，是由多径传播和多普勒频移两者共同作用的结果，包括由多径效应引起的衰落和信道时变性引起的衰落，具有信号的多径时延扩展特性和信道的时变特性(Fading is caused due to a slight change of the position of the space between the transmitter and the receiver, the characteristics of the receiving signal field strength, the instantaneous value of the rapid changes in the description within, by multipath propagation and Doppler frequency shift of the joint action of botha result, time-varying fading caused by multipath effects and channel fading due to multipath delay spread characteristics and channel time-varying characteristics of the signal)

本代码演示了将一个由非线性映射所产生的混沌序列作为载波，将待发送的有用信号(数字信号)作为调制信号，对非线性映射的某一参数在其混沌区域内进行调制的过程。另外，还有logistic相关代码(This code demonstrates a chaotic sequence generated by the nonlinear mapping as a carrier, will be sent a useful signal (digital signal) as the modulation signal, a nonlinear mapping parameters in the chaotic region is modulatedprocess.In addition, there are logistic related code)
