The Research Development of Unambiguous Acquisition Methods for BOC Modulated Signals

摘要

The Binary Offset Carrier (BOC) modulated signal, originating from the modernized GPS proposals, is a new signal type. The spectrum of BOC signal is dissociative, which can make full use of the existing spectrum resources. According to the present research status at home and abroad, four kinds of unambiguous acquisition methods of BOC signal and its development direction are discussed in detail. All methods are simulated and verified by Mat lab and the performance of their acquisition is analyzed.
