AM-and-FM-modulation

Computes the Discrete Fourier Transform of a function.

二用户CDMA系统，信道为加性高斯信道，使用BPSK调制，15位M序列扩频，可以正确解扩解调。 输出为2用户的基带信号、扩频信号、PSK调制信号、解调信号的时域和频域特性，给出两个用户分别的误码率。 (Second, the user CDMA system, channel for the additive Gaussian channel, using BPSK modulation, 15 M Sequence Spread Spectrum, you can correct demodulation despreading. Output of 2 user' s baseband signal, spread spectrum signal, PSK signal modulation, demodulation signal time domain and frequency domain characteristics of the two users are given the bit error rate, respectively.)

本程序用matlab编写，主要是为解决IEEE40节点电力负荷分配问题而想的一种算法。我把该算法命名为水桶法，是受一桶水的高度总与这个桶的最短一块木板齐平的原理，算法每次迭代把功率分配给需要最小消耗的机组上。(This program with matlab, main is to solve the IEEE40 node power load distribution and think of an algorithm. I put the algorithm named bucket method, by a bucket of water is the height of the barrels of the shortest total and a board at the principle, each iteration algorithm the power allocation to the minimum consumption on the unit needs. )

用于测定传递函数的matlab程序,可以直接调用用于测定传递函数(the basic funtion to get a system transfunction，and it can be called easily)

说明：  MATLAB写的差分进化算法，可用于做基本的配电网重构的问题，没有加IEEE3和6的(Differential evolution algorithm written by MATLAB)

说明：  时频分析方法是非平稳信号处理的一个重要分支，它是利用时间和频率的联合函数来表示非平稳信号，并对其进行分析和处理，利用时频分析法对语音信号进行去噪。(Non-stationary time-frequency analysis is an important branch of signal processing, it is the joint use of time and frequency functions to represent the non-stationary signal and its analysis and processing, using time-frequency analysis of the speech signal denoising. )
