the satellites constellation of BeiDou regional navigation satellite system (BDS) is different from GPS, which consists of Geostationary Orbit (GEO), Inclined Geosynchronous Orbit (IGSO) and Medium Earth Orbit (MEO). Due to the different constellation of navigation system, there should be some special characteristics of BDS to be analyzed thoroughly. For example, when used Ionosphere-Free Combination...
A multipath mitigation scheme based on BPSK-like technique and strobe pulse technique for sine-phased binary offset carrier (BOC) modulated signals is presented. Two kinds of strobe pulses are proposed, aiming to obtain the compromise between the pull-in region of the code discriminator and the tracking performances under thermal noise and multipath. Simulation results show that this technique only...
A novel multipath mitigation algorithm for multiplex binary offset carrier (MBOC) signals in the Global Navigation Satellite System (GNSS) is presented. Based on the W2 code correlation reference waveform (CCRW) structure, a series of bipolar reference waveform (BRW) are introduced to shape the unambiguous s-curve. The shaped s-curve has a single stable zero-crossing point, and the problem of unambiguous...
