Abstract

Abstract:

Multiple peaks of autocorrelation function of binary offset carrier (BOC) modulated signal can lead to ambiguity of signal acquisition. To solve the problem, a correlation multiplication side-peak cancellation technique (CMSCT) is proposed. Based on the special property of sub-correlation function of BOC signal, side peaks can be removed by multiplying different sub-correlation functions. Corresponding modified algorithm is presented for the purpose of taking full advantage of all received data to improve the acquisition performance. The complexity of the proposed algorithm as well as its detection probability based on the constant false alarm rate criterion are analyzed and compared with other algorithms. The result of using CMSCT for intermediate frequency sampling signal of Galileo E1C shows that the presented technique can effectively solve the problem of ambiguous acquisition.

Key words: global navigation satellite system, binary offset carrier modulation, unambiguous acquisition, correlation function, side-peak cancellation
