Research and analysis of BOC(1,1) multipath mitigation performance based on ASPeCT

Abstract

BOC(1,1) has a high accuracy of code tracking and perfect multipath mitigation performance as the main modulation of the next generation of GPS and the European GALILEO. Autocorrelation Side - Peak Cancellation Technique (ASPeCT) is specially design for BOC(1,1) code tracking loop and further improves the BOC(1,1) code tracking accuracy and multipath mitigation performance. In this paper, the multipath mitigation performance of ASPeCT applied to BOC(1,1) is researched and analyzed in case of the infinite bandwidth and limited bandwidth in consideration of the real channel properties. In the end, it gains the optimal correlating space and its corresponding minimum receiver bandwidth. © 2013 Springer-Verlag Berlin Heidelberg.
