An Improved PMF-FFT Acquisition Algorithm Based on Trigonometric Polynomial Interpolation

Published: 15 March 2023 Publication History

Abstract

Aiming at the problem of low accuracy of Doppler frequency offset estimation under the low SNR (Signal-to-Noise Ratio) condition of PMF-FFT acquisition algorithm, we propose an improved PMF-FFT acquisition algorithm based on trigonometric polynomial interpolation. Based on the PMF-FFT acquisition algorithm, the improved algorithm uses the differential coherent accumulation algorithm to process the PMF-FFT output results to improve the SNR of the signal, and uses the trigonometric polynomial interpolation algorithm to improve the Doppler frequency shift estimation accuracy. The simulation results show that the improved PMF-FFT acquisition algorithm effectively improve the SNR and accuracy of Doppler frequency offset estimation, without increasing the number of FFT (Fast Fourier Transform) operation points, and is more suitable for low SNR environments, ensuring the effective acquisition of the receiver loop in the low SNR environment, is of great significance to modern satellite communications.
