Abstract: In this paper we study two fourth-order cumulantbased techniques for the estimation of the mixing matrix in under-determined independent component analysis. The first method is based on a simultaneous matrix diagonalization. The secon is based on a simultaneous off-diagonalization. The number of sources that can be allowed is roughly quadratic in the number of observations. For both methods, explicit expressions for the maximum number of sources are given. Simulations illustrate,the performance of the techniques.
