New approach to blind deconvolution of single-input multiple-output - Linear FIR system

A new blind deconvolution scheme of linear single-input mull-output (SIMO) FIR system based on the isomorphism relation between the inputs and the outputs is proposed. The research shows that the system inputs can be identified blindly using only the output measurements under some constraints on the inputs and transfer function of a linear SIMO system. It is seen that the proposed blind deconvolution scheme offers lower computational complexity, better performance, and more robust against the over-determination of the system order compared with some conventional schemes.
