Verilog Code/ Algorithm for AM, FM and/or PM Demodulation

[reyge]

Does any one have a working Verilog code/ algorithm for envelope detection, phase discriminator and/or frequency discriminator? I already have a working code for demodulation of ASK and FSK but i dont think they'd work for their analog counterpart. Thanks.

Re: Verilog Code/ Algorithm for AM, FM and/or PM Demodulatio

this type of code is hard to find, because the code generally is proprietary.

Oh... I read a topic here about soft radios dated 2 years ago... i cant believe its still proprietary. perhaps there are public algorithms ^_^

I have done some research (inside and outside of the forum), some have implemented FM demodulation using all digital PLLs and FIR filters... I am leaning towards using them. My teacher suggested using FFT.. any comments about this? Thanks
