计算上田阵子的最大利亚普诺夫函数的matlab源码程序, 是确定系统的常微分方程。(the matlab code is using to caculat duffing the max lyapunvo about determined duffing system .)

代码实现了BPSK调制解调功能，包含成型滤波和硬判决模块。通过仿真出误码率曲线，并且画出理论曲线，验证了代码的正确性。(This code achieves the modulation and demodulation of BPSK.It includes the shaped filter and hard decision module.I plot the BER curve of BPSK and compared with the theoretical curve, I verify the correctness of the code.)

说明：  几点说明： 1、source_main.m为主函数，qpsk.m和spread.m为子函数； 2、在matlab工程目录下运行source_main.m即可； 3、为方便大家理解，特以P-CCPCH信道的处理进行了举例，若大家认为资料有用的话请回帖， 我会将整个WCDMA下行信号源的matlab代码提供给需要的人； 4、为方便初学者学习，特提供了我自己开发时参考的3GPP资料，并在关键位置做了记号。 (Some explanations: 1, source_main.m main function, qpsk.m and spread.m as Functions 2, matlab project directory can be run source_main.m 3, to facilitate us to understand, especially for P-CCPCH channel processing of the example, if we consider the information useful, please Replies, I will put the WCDMA downlink signal source matlab code available to people in need 4, for the convenience of beginners to learn, especially when providing a reference to my own development 3GPP information, and in key positions in the mark.)

常用的几个CSF函数（基于人类视觉特性的频域滤波函数），其说明在PDF文档之中(Top CSF function (the frequency domain filter function based on human visual characteristics ), which are described in the PDF document)
