Abstract
Two QPSK-like global navigation satellite system signals with unequal power are multiplexed as a constant-envelope signal analytically. It is further generalised as an extended AltBOC signal that has unbalanced power on the upper and the lower sidebands by the phase rotating technique. The modulations provide additional power control flexibility than the traditional DualQPSK and AltBOC signals and are demonstrated as optimum analytical implementations that maximise the power efficiency.
