- W2370679434 abstract "The FastICA algorithm is one of the most successful algorithms in blind source separation.It has a bright future in wireless communication due to its good performance in accurate separation and convergence.This paper analyzes the performance of FastICA algorithm when applied to noisy co-channel communication system.Firstly,we propose a model of ICA-based communication system,which adopts the FastICA algorithm to separate co-channel signals.In order to facilitate the analysis we first decompose the noise into two complementary subspaces,and get a new form of original signal through pre-whitening.Based on the analysis result above we obtain the analytic closed-form expressions of global separating matrix.Finally,a capacity index is brought forward to confirm the validity of our analysis and show the performance of ICA-based communication system.Some computer simulations that support the theoretical analysis are also included." @default.
