-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Nemanja,
uff, that's quite a lot of text I hardly understand. Could you please confirm: * You want to design a receiver * the receiver should have an Analog-to-digital converter * You already have a design for mixing from RF to baseband The rest I don't understand. What is your question? How is it related to GNU Radio? But it really does sound exciting!
