Could anyone please explain, in newbie terms, if it is possible to split a telemetry data stream from a satellite OBC into two data streams, sent simultaneously on two nbfm channels, each PSK with the phase difference between them? 

I have in mind a conversation which I don't fully understand, about these being the I and Q components, and this offering a doubling of the data rate compared with using one nbfm channel.

Grateful for any pointers on or off the -bb

many thanks
