AltBOC Receiver Design and Tracking Performance Analyze

The Galileo E5 signal is by far the most sophisticated signal among all the signals used for Global Navigation satellite system. Galileo receivers capable of tracking E5 will benefit from much better performance in terms of measurement accuracy and multipath suppression. Compared with traditional receivers for BPSK or even BOC signals, E5(AltBOC) signal processing techniques requires much more challenging due to the stems of the extremely large bandwidth and inherently complex correlations. This paper aims to present the receiving methodology and the architecture of tracking. The architecture of the tracking channel is discussed alongside with related algorithms and impact of code tracking jitter is evaluated finally.
