摘要：

Novel harmonic retrieval algorithm based on blind source extraction(BSE) method from linear mixtures of harmonic signals using only one observed channel signal is developed. Using the established BSE based harmonic retrieval model in additive noise, the fundamental principle of, BSE based harmonics retrieval algorithm is analyzed in detail. Then, based on the established harmonic BSE model, we propose a BSE approach to the harmonic retrieval using the concept of period BSE method, as a result, the harmonic retrieval algorithm using only one channel mixed signals is derived. Simulation results show that the proposed algorithm is able to separate the harmonic source signals and yield ideal performance.
