Abstract
Firstly we describe an improved POCET algorithm and design a multiplexing plan for B1 signals using it. At B1 frequency, binary complex subcarrier is chosen to implement the center frequency difference between regional and global navigation systems. Regional BPSK(2) OS signal and global TMBOC signal are combined and the best multiplex efficiency is −1.010 dB. Regional BPSK(2) AS signal and global BOC signal are combined and the best multiplex efficiency is −1.593 dB. And then, we analyze the signal in band-limited systems from three aspects: multiplex efficiency, constellation diagram and signal’s peak to average power ration (PAPR). And then, we analyze the multiplex signal in band-limited system from three aspects: multiplex efficiency, constellation diagram and signal’s peak to average power ration (PAPR). The ideal constant-envelope signal has become nonconstant-envelope of which constellation has changed and PAPR has increased. Also the multiplex efficiency has decreased, and it has decreased more after 30 MHz filter by almost 0.55 dB. The results of this paper provide the constant-envelope multiplex scheme at B1 frequency and the multiplex efficiency, and the analysis in band-limited system which is of significance in engineering practice.
