Abstract
The Multiplexed Binary Offset Carrier (MBOC) signal has been recommended as optimized modulation on L1/El frequency band by both United States and European Union communities. MBOC signal is defined on the basis of its spectrum, while different time waveforms can be selected as possible modulation candidates. In this paper we present the different options of the new optimized MBOC signal in both time and frequency domains in order to analyze their performances in terms of tracking accuracy, thermal noise and multipath-induced pseudorange error. A comparison between the MBOC options and the baseline signal BOC(1,1) is also presented based on software simulation results to illustrate that the use of MBOC signal for GPS and Galileo satellite navigation systems is an opportunity to provide the best possible performances for evolved receivers.
