I am writing code for multi-carrier data transmission over time varying multi-path channel in MATLAB. Mathematically , received signal can be represented as,
y=x(t)*h(t,delay)+n(t)
Impulse response of channel with 5 multiple paths has been designed in this work. complex gain and delay of multiple paths have also been calculated. Since channel is time varying the size of transmitted signal and impulse response of time varying channel are different. Please anybody tell me how to transmit the signal through time varying channel having multi-paths in MATLAB
Respected Ma'am,
The equation you shared it's generalized version of a received signal. For a time varying channel you can have a look in this link

I hope it will give you an idea to work further.
Thank you
Hello,
Maybe you can look for Rappaport wireless communications book, he show how it works, and the code is esay when you understand it!

look for this book chapter
Chapter Mathematical Model of the Time-Varying Wireless Channel
