Abstract
In this paper, we introduce a new tensor model for the 4th-order space-time output cumulants in the context of convolutive MIMO linear systems. We also propose a single-step least-squares (SS-LS) algorithm for blind identification of convolutive MIMO linear systems. The proposed tensor-based identification algorithm generalizes our methods recently developed for SISO and memoryless MIMO linear systems. Uniqueness conditions are derived showing that a large range of system configurations can be considered. Simulation results illustrate the performance of the proposed algorithm.
