基于多相结构的信道化发射机实信号输出matlab仿真程序:从仿真得到的图可以看到，输出8路实信号所需的带宽为输出8路复信号所需带宽的一半。另外，输出的复信号频谱结构不再像直接法实现时所得到的顺序对应结构，其原因还有待进一步研究。(Channel based on multi-phase structure of real signal of the transmitter output matlab simulation program: graph obtained from the simulation can be seen, the output 8-channel bandwidth needed for real signals, the output 8-channel half the bandwidth required for complex signals. In addition, the output structure of the complex signal spectrum is no longer realized as the direct method corresponds to the order obtained by the structure, the reason remains to be further studied.)

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)

In this paper, an attractive approach for teaching genetic algorithm (GA) is pre-sented. This approach is based primarily on using MATLAB in implementing the genetic operators: crossover, mutation and selection. A detailed illustrative example is presented to demonstrate that GA is capable of finding global or near-global optimum solutions of multi-modal functions. An application of GA in designing a robust controller for uncertain control systems is also given to show its potential in designing engineering intelligent systems
