| 中文摘要 | The frequency track method for the Chinese national standard on terrestrial digital television broadcasting system (DTMB) is analyzed and then an improved high-precision approach based on Kalman filtering is proposed in this paper. Simulation results show that the proposed method possesses two strongpoints respectively shared by two different conventional track loop with different loop-bandwidth: fast convergence speed and low frequency jitter, and also provides much higher precision compared with the conventional method. |
