Title:
SYSTEM AND METHOD FOR FREQUENCY ESTIMATION
Document Type and Number:
WIPO Patent Application WO/2016/197629
Kind Code:
A1
Abstract:
A method for reconstructing a signal is provided. The method may include determining a first function indicative of the signal, and initializing a missing pattern relating to the first function, under the impulsive noise condition. Noise reduction can be performed by solving an estimation problem utilizing the sparse structure of the noise in the time domain. An iterative estimation of frequency and missing pattern in the case of the impulsive noise may be conducted as follows: during each of a plurality of iterations, conducting a frequency and a noise estimation of the signal at each successive iteration based on the initialized or a prior calculated missing pattern, and conducting a missing pattern estimation based on the estimated frequency and noise and the first function generating at least one of a reconstructing the signal based on the estimated frequency, the estimated missing pattern, and the estimated noise.
