idea here. I don't know what functions are available in a FPGA, but think all the way to the antenna. Perhaps samplers, perhaps numerically controlled oscillators for the DDS (accumulator and delta_phase register), perhaps A/D functions are available or can be implimented. And then on to the MAC , DSP etc. It's well worth looking in to :-) Thanks for your thoughts, Regards, John ----- Original Message -----

That way only logic functions specific to the SDR application need be present. Things like cost and power requirements would have to be looked at but if there is some interest in this I might place it higher up the stack of things to do. 73 de Phil N8VB |
