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). Mike Smith |
