    Abstract
  • As least square (LS) method, which is applied to precise measurement of PN sequence phase in high-accuracy, is limited in narrow range condition of coarse synchronization, it is difficult to satisfy the needs of practical project. A novel realized structure of accumulative LS method for PN sequence phase measurement is presented. According to the characteristic of phase discrimination curve, the accumulative maximal value and minimal value of the phase discrimination curve are viewed as the characteristic reference position, and the samples between the maximal value and the minimal value are fitted by LS method. A high-accuracy measurement of the PN sequence phase can be achieved in half-width of the chips under the condition of coarse synchronization. It is proved that the characteristic of phase discrimination is linear in theory, and can use accumulative LS method suitably. The simulation results indicate that the proposed method has wider range of coarse synchronization and higher measurement precision.
