MATLAB Online에서 열기 다운로드 This code demonstrates using the least mean squares (LMS) algorithm to perform equalization in a communication system. The code generates a QAM-modulated signal, applies a channel impulse response, adds noise, and performs LMS equalization to recover th...
The purpose of this project is to provide a plot of the Chanel Impulse Response in a use-case scenario of your choice. This folder provides a Matlab function and an example of using it. The "getCIR.m" function imports the CIR values generated by a ray tracer. In our case, it is ...
The coefficients are saved in the text file that you specified, and the MATLAB Editor opens to display the file. The text file also contains comments with the MATLAB version number, the Signal Processing Toolbox™ version number, and filter information. ...
