| Abstract: | This paper presents a 2nd phase system model and its Kalman filtering algorithms. Their performances are simulated. The optimized parameters are obtained. The algorithm ability to follow the tracks of higher phase variety in the practical environment is confirmed by adding a sinusoidal frequency instigation to the filter input. These algorithms provide an effective approach for the all-digital receiver to achieve carrier synchronization without carrier loop. |
