Abstract Based on higher-order cumulants, the blind estimation of complex mixed matrix for the difficult case of 2 sensors and 3 sources is addressed. When the number of source signals is greater than or equal to the number of sensors, the proposed algorithm can successfully estimate the channel matrix. The performance of the algorithm is evaluated by computer simulation.
