　　More and more signals are broadcast by navigation satellite systems nowadays to satisfy users' diversified needs in positioning,navigation and timing(PNT).We usually adopt multiplexing techniques to combine several signals into an integrated signal to save transmission link resources.Since the high-power amplifier on satellite operates at the nonlinear saturation region,the multiplexed signal is required to have constant-envelope characteristic.
