Hello,

Suppose that the channel impulse response is (written in LateX syntax)

h(\tau)=sum_{p=1}^{N_p}h_p \delta(\tau-\tau_p)

and the OFDM transmitted signal is

s(t)=\Re\{\sum_{k=0}^{K-1}s_k e^{j2\pi f_k t}\}

Then, the noise-free received signal will be:

r(t)=\Re\{\sum_{k=0}^{K-1}s_k\sum_{p=1}^{N_p}h_p e^{j2\pi f_k(t-\tau_p)}\}

How can I generate this OFDM received signal in MATLAB?

I appreciate any help

Note: there have been over 50 requests for OFDM code posted over the last few years. Most of them have gone completely unanswered. Only one bit of OFDM code comes to mind as having been posted in the last year, and that code was not working code.

You could start looking through some of the past requests, but history suggests that there will not be much answer from the volunteers. The most active volunteers do not happen to work on communications systems.

Thanks for notifying me about this. I thought this community would include active users from all sort of specializations, and I was hoping to find answers to my technical questions here.
