A Novel Carrier Tracking Loop Based on Three-Stage Bandwidth KF
Pages 828 - 832
Abstract
In response to the situation where the carrier tracking loop based on standard KF still cannot effectively suppress noise in steady-state, this paper proposes a novel carrier tracking loop based on three-stage bandwidth KF. The bandwidth of the loop is dynamically adjusted in three stages, ensuring that its loop filter can quickly lock in high dynamic signals with wide bandwidth in the early stage and further reduce the impact of noise with narrow bandwidth in the later stage. This has significant application value in deep space communication with high robustness requirements.
