Seri port kullanı mı usage of serial port on matlab

说明：  信号加噪去噪的处理，在MATLAB中可以试听各阶段声音(It can be used for signal denoising and processing, and can be used to listen to the sound of each stage.)

In this Matlab Code we Introduce method you can Descriting Any Continous System transfer function to Descrite time transfer function by Sampling from Continous System. this method is Simple And Useful For Some program that start with Descriting. and the other file is one example from its application.

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)
