Hi John, Thank you for clarifying the openness of the transmission format. Could I ask whether there is any scenario under which aspects of the signal transmission design might be patented? If companies or individuals wish to patent aspects of receiver design, that's fine, but I'd be uncomfortable with a patent-encumbered transmission format.

I suppose it's a matter of balancing the value of the PLL receivers and the loss of BPSK signal power to the residual carrier. If the power loss is small, though, say 0.5 dB or below, then given the large process gains of the advanced receivers, it might be worth considering. I don't imagine that the mere presence of residual carrier has any effect on the advanced receivers (since it is similar to interference from MSF and JJY, as you say), but please correct me if I'm wrong.
