Hello i need to simulate two moving car communicaiton using ofdm i did ofdm part but how can i add dopplershift frequncy to my channel without using comm.Rayleighchannel. if i use comm.Rayleighchannel how can i equalize it.

Hi Emirhan,
I understand that you wish to add Doppler Shift to your channel without using "comm.Rayleighchannel".
You can apply a frequency offset to your OFDM signal to add Doppler shift to your channel without using "comm.Rayleighchannel". This frequency offset represents the Doppler shift due to the relative motion between the transmitter and receiver.
To add the frequency offset, you can use the "comm.PhaseFrequencyOffset" System Object. The frequency offset is specified in Hz, and can be calculated from the relative velocity between the two cars and the carrier frequency.
I hope this helps!
