FSK adding I&Q correctly in phase and amplitude

I've done an FSK decoder that already works very well but there is a request to enhance the sideband surpression. the transmitting part encodes its binary stream with fsk, where it sends out tw...

I am not sure what you are after.

your FSK is based on I/Q channels from ADC (so it is eqiuvalent to any complex signal at Rx).

The IQ are needed to get f0/f1. You shouldn't change them.

May be you are after removing RF sideband. In that case the RF people should do their job better else you remove it if you hve enough speed.
