Blind equalizations based on effective channel order determination for multiple FIR channels

This work deals with the problem of blind equalizations based on effective channel order determination for multiple FIR channels. Most popular order determination methods use the eigenvalue decomposition (EVD) technique to an overmodeled data correlation matrix. However, performing the EVD consumes huge computation resources. In this paper, we consider the channel with infinite small leading and tailing terms which is natural for measured microwave radio channels and develop a computationally simple method for effective channel order determination. This proposed method does not require EVD, the computation load is much lower than that of the EVD-based methods.
