WebAssuming the background noise as Gaussian distribution and Laplace distribution, the new method firstly performs auto-correlation and cross-correlation operation on the received signal to suppress noise initially, and then performs fourth order cumulant operation to further suppress noise and finally extract time delay information by cross ... WebThe cumulants give a measure of the (non-)Gaussianity of the components. As explained earlier, the fourth-order tensor of loadings cumulants can be seen as a generalization of the second-order variance–covariance matrix. Independent vectors have null cross-cumulants and maximal auto-cumulants.
