Abstract
A scheme is proposed for selective application of CFO (Carrier Frequency Offset) to a pair of navigation satellite signals in orthogonal phase relationship at CEM (Constant Envelope Multiplexing.) The proposed scheme has low implementation complexity and can be useful in signal design for a new navigation satellite system using a frequency band where the spectra of the existing legacy signals are asymmetrically distributed in frequency. When the signal pair for CFO are bi-phase signals with equal power, the proposed scheme is especially attractive since the same CEM scheme can be used as that without the selective CFO.
