Strobe Pulse Design for Multipath Mitigation in BOC GNSS Receivers

F. M. Sousa, F. D. Nunes and J. M. Leitao

Abstract:	Binary offset carrier (BOC) modulations have been considered for the new GNSS signals since they achieve better tracking performance than PSK in the presence of channel noise and multipath. Besides, the concept of delay lock-loop based on symmetrical strobe pulses can be extended to BOC signals with significant advantage in the close-in multipath region. Herein, a new approach to the design of asymmetrical strobe pulses for BOC signals is proposed. A target code discriminator response with desirable characteristics is defined allowing to determine the strobe pulse as the solution of an integral equation. The resulting pulse provides good multipath mitigation capability, extended code tracking range, and lack of false code lock points.
