Area estimation of time-domain GNSS receiver architectures

This paper presents the silicon area estimation of three different GNSS receiver architectures with the analysis of four different use cases. The receivers are based on traditional correlator, matched filter, and group correlator architectures. While introducing the selected test cases, the authors discuss their applicability for real-life receiver operations. The receiver architectures are described shortly and the implementation details explained. The comparison shows that the correlator based receiver suits best for tracking while matched filters are efficient only for pure search mode. The group correlator offers a good area-efficiency in both tracking and search modes.
