Blind source separation utilizing a spatial fourth order cumulant matrix pencil

The narrowband of the state a signal and clamping noise ratio blind source of counting relatively independent signal end of the BSS) technology and by spectrum estimation of cumulant and signal loop subspace blindly. The BSS technology of high-order counting method, and fourth-order cumulant, and lower end of matrices generalized for intrinsic to unknown, the counting relatively independent, a low voltage signal and noise) and a ratio narrow-band signal loop blindly, and time information Gaussian noise end of the signal of the surface and/or a. The BSS technology claims, wherein without a bidirectional technique is used for part in the condition of said separation is placed on the blind of a method, for example a low signal-to-noise ratio, wherein the source of equal to of the sensor of the noise of the space and time colour noise condition.
