A Robust BOC Code Tracking Technique in Non-ideal Channel

摘要

Most unambiguous tracking techniques for the new binary offset carrier (BOC) modulated signals have unexpected false lock points or a considerable tracking bias in non-ideal channel. A new BOC tracking technique is proposed, which approximate upper and lower sideband of BOC signals as bi-phase shift keying (BPSK) like signals. Due to BPSK signals inherent insensitivity to channel imperfections, the proposed method can track robustly under practical channels.
