Ranging Performance Evaluation for Higher-Order Scalable Interplex
Abstrak
Scalable interplex represents a multiplexing technique that has been specifically designed to modify a signal constellation in order to adapt the transmitted signal to the characteristics of a high-power amplifier and thereby enhance the received power of the navigation signals. This paper builds upon existing knowledge regarding the trade-off between increased usable signal power and amplifier efficiency when scaling intermodulation (IM) terms, with a particular focus on the Galileo E1 signals and one potential additional signal candidate. The scalable interplex is optimized based on the achievable joint receiver efficiency. The aim of this study is to determine whether this signal constellation optimization also results in a reduction in code tracking jitter. The findings indicate that in numerous instances, the scalable interplex achieves a reduction in code tracking jitter by scaling specific IM terms in comparison with a constant-envelope six-channel interplex.
