In this paper, a new efficient adaptive filtering algorithm belonging to the Quasi-Newton (QN) family is proposed. In the new algorithm, the involved inverse Hessian matrix is approximated by a proper expansion, consisting of powers of a Toeplitz matrix. Due to this formulation, the algorithm can be implemented in the frequency domain (FD) using the fast(More)
In this paper two new adaptive equalizers are proposed which belong to the quasi-Newton (QN) algorithmic family. The first algorithm is a Linear Equalizer (LE) and the second one is a Decision Feedback Equalizer (DFE). In the LE case the involved inverse Hessian matrix is approximated by a proper expansion consisting of powers of a Toeplitz matrix. Due to(More)
