摘要
En 中文
Based on the concept of pseudo correlation function (PCF), we propose an unambiguous tracking method for alternative binary offset carrier (AltBOC) modulated signal, which is employed in global navigation satellite system. The proposed method employs two specifically designed chip spreading symbols for local reference signals to generate a no side-peak function instead of the original multiple-peak auto correlation function (ACF) for tracking. Results demonstrate that the code tracking and multipath mitigation performances of the proposed method are better than the BPSK Like method on the whole.
