A new approach to blind separation of overdetermined mixtures
Jie Yang, Jiashu Zhang · 2007
Different from the general way to overdetermined blind source separation problem whose demixing matrix is a nonsquare one just as the mixing matrix, this paper proposed that using n (the number of sources) elements of the mixture signals as the new mixture signals to be separated, this means, the dexmixing matrix becomes a square one.First, the simulation shows the new approach works efficiently as the general approach.Second, the feasibility of the new approach is proved by comparing the entropy of the different mixtures.Finally, some interesting conclusions are obtained.
