Abstract

This chapter offers a detailed discussion of the typical constant envelope multiplexing (CEM) techniques for satellite navigation spread-spectrum signals, such as QPSK multiplexing, time division multiplexing, quadrature product subcarrier modulation (QPSM), Interplex, phase-optimized constant-envelope transmission (POCET), constant envelope multiplexing via intermodulation construction (CEMIC), majority voting (MV) multiplexing, and asymmetric constant envelope BOC (ACE-BOC) multiplexing. Some of these techniques have been used in satellite navigation systems currently in operation, while others have good application prospects in future system construction. The content of this chapter is not a simple list of the various technical implementations. We will focus on the principles of these constant envelope multiplexing methods and the design concepts behind the development process,in order to understand the implementation details of each technique, and to display the essential connections between them. This allows us to offer a more systematic understanding of the research field to readers. Remaining challenges in this field are also discussed in the end of this chapter.
