I've just studied FPGA for a short time. At that time, I've built successfully a QAM-16 modulation project using VHDL code. But now, when I try to build QAM demodulation, I've met a big problem. I've done the demodulation in matlab, but in FPGA, I can not synchrolize the receive signal with the carrier recovery. I mean I can't recover symbol clock from receive signal. That's why the demodulation didn't work.
Please tell me if you have any advice, code or material about my problem.
