GNSS Signal Design Approach Considering Receiver Performance

Antreich, Felix and Nossek, Josef A. and Issler, Jean-Luc (2008) GNSS Signal Design Approach Considering Receiver Performance. In: NAVITEC 2008. NAVITEC 2008, 2008-10-12 - 2008-12-12, ESA-ESTEC Noordwijk, The Netherlands.



In this work we establish a systematic approach to design optimum chip pulse shapes for DS-CDMA systems which are absolutely band-limited, whose energy is mainly concentrated in one chip duration, and that minimize the Cramer-Rao lower bound for the time-delay. The proposed methodology makes it possible to formulate the problem of designing optimum chip pulse shapes in terms of achieving a trade-off between synchronization accuracy and acquisition and tracking robustness as an optimization problem. Additionally, spectral separation to non-interoperable signals in the same band is considered. This methodology is based on the prolate spheroidal wave functions (PSWF), which enable to transform the primal variational problem into the dual, tractable parametric optimization problem. This work shows the interesting capabilities of the presented signal design approach for DS-CDMA systems. This methodology is further developed according to the needs of Galileo-2 signal design.
