OFDM implementation over rayleigh channel with doppler , matlab(simulink) to hdl

Is there a way to simulate ofdm over a rayleigh channel with doppler , using matlab functions /simulink(blocks), which are compatible with hdl coder , to implement on an fpga?

Hi @Siddhardha ,

Addressing your query regarding, “ But my main issue is that i need a block which includes rayleigh channel and which includes effects of doppler effect”

Why not use rayleighchan function to create a Rayleigh fading channel object & adjust the Doppler frequency fd to introduce Doppler effects into the channel model utilizing the Communications Toolbox. For more information on this function, please refer to

Please let me know if you have any further questions.

Thank you for your answer.

But,my main issue is that i need a block which includes rayleigh channel and which includes effects of doppler effect,

I have found this example

https://in.mathworks.com/help/wireless-hdl/ug/hdlofdmmatlabreferences.html?searchHighlight=whdlexamples.hdlawgn&s_tid=srchtitle_support_results_2_whdlexamples.hdlawgn

which uses hdl ofdm transmitter and reciever blocks to simulate over an awgn channel ,but are there any blocks availble for rayleigh channel, which also include the effects of doppler?

You can check this example from the Wireless HDL Toolbox.
