一种改进的基于多段信号融合的频率估计算法
Improved Algorithm for Frequency Estimation by Fusing Multi-segment Signals
摘要
Abstract
In the frequency estimation of multi-segment signals, the error caused by discontinuity among different segments cannot be ignored. By correcting the phase difference of each segment, the results can be enormously improved, but the computational complexity of the algorithm grows at the same time. To resolve this problem, a new fusion algorithm based on spectrum zooming is proposed. The new algorithm performs spectrum zooming analysis to reduce the computational complexity while the precision is guaranteed. Results show that the algorithm is suitable to those real-time applications.关键词
