The second thing I want to do is detecting if multiple transmitters (at
different locations and frequencies) transmit the same radiostation.
With a single tuner I can capture all these signals at the same time.
Provided they are within 8 or 16MHz.
Then do a correlation to get there phase and time relationship.
And then smartly combine them to get better signal quality.
Clever boy!
Do you have in mind that RD(B)S transmits "alternative frequencies"?
This is a feature to enable seamless frequency switch for mobile users
(cars). Never thought of it to use it simultaneously.
This would spare you a lot of correlation.
Do you have some code already?
