Paper Abstract

In high dynamic environments, signals in low earth orbit (LEO) satellites and terrestrial communications have large Doppler shifts. Traditional carrier tracking loops based on multi-stage frequency-locked loops and phase-locked loops perform poorly. In recent years, particle tracking based carrier tracking loops have been brought into consideration. In this paper, the standard particle filter (PF) and unscented particle filter (UPF) are analyzed in principle, and based on this, an improved unscented particle filter algorithm is derived, and the carriers based on these three algorithms are derived. The tracking loop is simulated by MATLAB. The new algorithm reduces the complexity of the UPF algorithm under the premise of ensuring accuracy.
