The application of blind signal separation in mobile communication

Based on the analysis and introduction of blind source separation, it analyzes the signal sorting of the maximum kurtosis natural logarithm, compares the signal model forms of the narrowband blind beam forming and instantaneous hybrid model of blind source separation and those of the broadband blind beam forming and convolutive hybrid model of blind source separation, and obtains the conclusion that the broadband blind beamforming and convolutive hybrid model of blind source separation can adopt the same signal model. It finally proposes a model for the broadband smart antenna of blind adaptive beamforming device.
