Blind-source-separation algorithm based on bounded-component analysis
Chuen-Yau Chen, Wei-Ching Liu, Bo-Wei Lin, Cheng-Yuan Lin · 2016
In this paper, we proposed the relative-gradient bounded component analysis algorithm using the relative gradient to find the maximum value of the objective function. The algorithm does not need to compute the inverse matrix and the covariance matrix, and it can separate the mixed signals without whitening. The time complexity and the space complexity of this algorithm are both lower than those of the original BCA.
