摘要The null space pursuit (NSP) algorithm is an
operator-based signal separation approach which separates a
signal into a set of additive subcomponents using adaptively
estimated operators. In this paper, we introduce a multi-operator
based strategy and propose multi-operator based null space
pursuit (MONSP) algorithm for signal separation. On the one
hand, the proposed approach is a generalized formulation of the
original work in some sense. On the other hand, compared with
the NSP, the proposed approach has its intrinsic advantages:
1), the proposed approach avoids the mode-mixing problems
which is often meet in NSP algorithm; 2), the multi-operator
based formulation could theoretically reach the ideal separation
resolution for the noise-free signal separation; 3), the MONSP
algorithm does not need to initialize parameters in each iteration.
We perform several experiments on synthetic and real-life signal
separation by MONSP and compare some results with the stateof-
the-art methods to demonstrate the efficiency and robustness
of the proposed method.
