Abstract :
A new constant-envelope modulation multiplexing two quadrature phase shift keying (QPSK)-like global navigation satellite system (GNSS) signals and its generalised form with unbalanced power are presented. The modulations can be regarded as the extended form of generalised DualQPSK modulations and provide a solution to the Compass B1 band multiplexing problem.
