Abstract:
本申请公开了一种双频恒包络导航信号的生成方法、生成装置、接收方法和接收装置。该双频恒包络导航信号的生成方法包括：在上边带子载波和下边带子载波上分别调制正交导航信号，其中，上边带子载波和下边带子载波的最小符号长度为子载波周期的1/4。根据本申请，可以获得一种低复杂度的双频恒包络导航信号的生成和接收方法及装置。
Abstract(English):

The invention discloses a double-frequency constant envelope navigation signal generation method and generation device and receiving method and receiving device. The double-frequency constant envelope navigation signal generation method comprises the steps that an orthogonal navigation signal is modulated on an upper sideband subcarrier and a lower sideband subcarrier, wherein the minimum symbol length of the upper sideband subcarrier and the lower sideband subcarrier is 1/4 of the subcarrier period. According to the application, the low-complexity double-frequency constant envelope navigation signal generation and receiving method and device can be obtained.
