how to realize demodulation module in FPGA

hi everyone, i want to realize demodulation module in EP2C35 with verilog code,the frequency of carrier wave is 10KHz, and the frequency of modulation wave is 2.5MHz. what method or algorithm is...

The signal flow is as following:

analog signal from Ultrosonic Probe -> A/D -> FPGA(using digital demodulation shceme)

Generally,Hillbert convert is used to demodulation,but it is difficult to be realized in FPGA,i think.So I am searching other ways which are not so difficult.

Thank you Dave for the material you provided.
