Universal FIR MMSE Filtering

T. Moon, T. Weissman
2009 IEEE Transactions on Signal Processing  
We build a universal filter whose per-symbol squared error, for every bounded underlying signal, is essentially as small as that of the best finite-duration impulse response (FIR) filter of a given order  ...  Our analysis combines tools from the problems of universal filtering and competitive on-line regression.  ...  Naturally, we try to merge the methods of [11] and [13] in developing our universal FIR MMSE filter.
