HDL QAM Transmitter and Receiver simulation problem

Hi

hope you are all doing well.I am working on HDL QAM Transmitter and Receiver to generate hdl code for transmitter and receiver also with testbench for both TX and Rx.when i am going to simulation in vivado HDL QAM TX and RX with these own testbench generated from matlab its working fine but when i going to give the input signal from my own code writen to tx then TX ip working well and ii directly connected the output of TX with the input of RX .TX output is same like matlab testbench and RX not giving me output desired signal.

kindly assist me how i will solve my issue.

thanks and regards

Ali

Hi Ali,

I connected HDL QAM Transmitter and Receiver back to back, it is working. If your Tx code exactly matches with the HDL QAM TX, the receiver should decode properly. Can please make sure both Tx outputs are matched.

Let me know if your problem is different.

Thanks,

I have given clk of 100Mhz and Rset signal 1 for 20ns(for two clock cycles) and then goes to zero and after 10 ns Clock Enable becomes 1 i.e total of 30ns (3 clock cycles) .

Both clk enable and reset are directly connected to TX and RX IPs.

Is it correct or not?

Also can we run this design for low data rates upto 10kbps or not?

@Kranti Balaga your kind response is still awaited.

Sorry for delayed responce. Presently the model simulates for fixed sample rates. If you want to modify the sample rates/data rates, adjust the model accordingly.

Thanks,

Even on fixed sample rate we are not getting the desired output . Can you please tell whether our technique is correct or not as explained in the previous comment
