摘要：
In this paper, a novel algorithm based on subspace projections is developed for blindly estimating the discrete orders of a linear finite-impulse-response (FIR) multiple-input multiple-output (MIMO) system, the number of subsystems that attain each order as well as the total number of inputs. Furthermore, the proposed algorithm applies to single-input multiple-output (SIMO) system order estimation. Simulations in the context of blind channel order estimation show good performance in comparison to existing schemes developed for SIMO systems.
