Physical interpretation of signal reconstruction from reduced rank matrices
Ioannis Dologlou, G. Carayannis · IEEE Transactions on Signal Processing · 1991
An enhanced version of a signal is obtained after subtraction of a linear combination of rank one matrices from the signal observation matrix. This operation results in a nonToeplitz observation matrix. By averaging the elements of this matrix, a new Toeplitz matrix is produced and a reconstructed signal is generated. This averaging operation is examined, and physical interpretations are given.>
