A method of a satellite navigation signal generation device, comprising:
- receiving a plurality of signals;
- assigning carrier frequency offset(s) to at least one pair of signals among the plurality of signals;
- and
- generating a constant envelope multiplexed signal for the plurality of signals including the at least one pair of signals to which the carrier frequency offset(s) are assigned,
- wherein the assigning of the carrier frequency offset(s) comprises:
- switching the at least one pair of signals among the plurality of signals between an in-phase channel and a quadrature-phase channel according to a change in a sample period;
- and
- sign-inverting the at least one pair of signals switched to the in-phase channel or the quadrature-phase channel.

A device for generating a satellite navigation signal, comprising a processor,
- wherein the processor causes the device to perform:
- receiving a plurality of signals;
- assigning carrier frequency offset(s) to at least one pair of signals among the plurality of signals;
- and
- generating a constant envelope multiplexed signal for the plurality of signals including the at least one pair of signals to which the carrier frequency offset(s) are assigned,
- wherein in the assigning of the carrier frequency offset(s), the processor causes the device to perform:
- switching the at least one pair of signals among the plurality of signals between an in-phase channel and a quadrature-phase channel according to a change in a sample period;
- and
- sign-inverting the at least one pair of signals switched to the in-phase channel or the quadrature-phase channel.
