Abstract :
The letter deals with the efficient determination of FIR Wiener filters with linear phase. This task is achieved by exploiting the Toeplitz-plus-Hankel structure which is imposed on the normal equations matrix by the phase linearity constraint and the stationarity assumption. It is shown that the design of these filters is ultimately reduced to the computation of optimum FIR Wiener filters by Levinson´s algorithm.
