Abstract
In next generation GNSS signal design, the increasingly various services draw a strong demand to the technique of multiplexing, among which the dual-frequency constant envelope multiplexing is one of the hottest issues and has been attracted great attention from researchers and system builders. ACE-BOC is a recently proposed technique, which allows the multiplexing of four or less arbitrary signals into a composite signal with constant envelope. In this paper, an optimization based low-complexity simplification is made for ACE-BOC. To meet the design requirements and constraints of BeiDou satellite navigation system (BDS), a typical implementation for B2 band is provided by using the optimized ACE-BOC. Analyses show that the optimized ACE-BOC achieves superior tracking performance to other representative dual-frequency CEM such as AltBOC and TD-AltBOC, and has equal or lower complexity in the implementation of signal generating. The optimized ACE-BOC provides a competitive alternate for BDS B2 signal with good performance on both transmitter and receiver.
