In this paper, MBOC (Multiplexed Binary Offset Carrier) Signal which is recommended as the optimized modulation on L1 (E1) frequency band by both US and EU sides in the future was studied. This paper carried on the detailed analysis to the new MBOC signal characteristic through the analysis of the power spectral density function. Then two multipath mitigation techniques based on DLL (Delay Lock Loop) — strobe correlator and narrow correlator with basic functionality and implementation were introduced. These two techniques were applied to mitigate the multipath's influence on MBOC signals. Simulation based on Matlab tool was analyzed and the performance was compared with the BOC signals.
