Building a DAB radio
Hello,
has anyone come across any projects or info on building your own DAB radio.
This is my (limited) understanding:
How it's sent: The audio (or whatever) signal is split and sent using
Quadrature Amplitude Modulation over many narrow band carriers (each
carrier at a different frequency): Ie it's spread spectrum. Error
correction Coding is also used, etc.
To decode it: This is where I'm confused; Can I build a receiver which
will receive the whole collection of narrow band carriers, then feed it
into a computer that will do some FFT?
Not really sure how to move forward; any ideas would be fantastic.
Thankyou all!
(PS It's good to see there's a newsgroup on this topic).
