Multipath Fading Channel Model with Xilinx System Generator

[KHEDDARARANIA]

hello i want to work with Rayleigh fading channel model in Matlab 2013 and Vivado2015.1  but i couldn't find the provided model can you send it to me?

Unfortunately xilinx does not have sysgen demo for Rayleigh fading channel model. 

You may check if Matlab has a demo for it, then convert this demo to sysgen design.

Thank you for answering my question; i also need a QPSK demodulation model, i did find the modulation model but without the demodulation part can you tall me where i can find it ?
what did you mean by ' then convert this demo to sysgen design' how we can do that ? and thanks in advance.

 Can you clarify your question "i did find the modulation model but without the demodulation part can you tall me where i can find it ?"

Assuming the matlab design is a simulink model, it's floating point data type and does not use Xilinx sysgen blocks, the converting just means you need to use Xilinx sysgen blocks to replace the simulink blocks, and sometimes you need to use fixed-point data type in the sysgen blocks to replace the previous floating point data type.

i need the demodulation model for this modulation model (QPSK). https://www.mathworks.com/matlabcentral/fileexchange/14650-digital-modulation-in-fpgas-xilinx-using-system-generator-ask-bpsk-fsk-ook-qpsk
