一个matlab实现bp的源文件，也许各位用得上，请大家多多指教(Bp realize a matlab source files, perhaps you useful, please everyone exhibitions)

计算信噪比，计算公式是信号能量比上噪声能量(SNR Calculation，signal power divide noise power)

基于AM DSB SSB调制解调的程序，较好的组织了语言描写，展示了通信系统中最基本的调制解调过程知识(Based the AM DSB SSB modulation demodulation process, preferably organized language description, showing a basic knowledge of the modulation and demodulation process in the communication system)

局部均值分解是由Smith提出的一种新的非线性和非平稳信号分析方法。由于LMD是依据信号本身的信息进行自适应分解的，产生的PF分量具有真实的物理意义，由此得到的时频分布能够清晰准确地反映出信号能量在空间各尺度上的分布规律。(Local mean decomposition is a new nonlinear and non-stationary signal analysis method proposed by the Smith. Since LMD information is based adaptive signal itself decomposed, resulting PF component has real physical meaning, when the resultant frequency distribution of the signal can be clearly and accurately reflect the spatial distribution of the energy of each scale.)
