dc.description.abstract

In this paper, a nonlinear phase finite impulse response (FIR) filter is de-signed without imposing a desired phase response. The maximum passband group delay of the filter is minimized subject to a positivity constraint on the passband group delay re- sponse of the filter as wel l as a specification on the maximum absolute di?erence between the desired magnitude square response and the designed magnitude square response over both the passband and the stopband. This filter design problem is a quadratic NP hard functional inequality constrained optimization problem. To tackle this problem, first, the one norm functional inequality constraint of the optimization problem is approximated by a smooth function so that the quadratic NP hard functional inequality constrained optimization problem is converted to a nonconvex functional inequality constrained op- timization problem. Then, a modified fil led function method is applied for finding the global minimum of the nonconvex optimization problem. By using a local minimum of the corresponding unconstrained optimization problem as the initial condition of our pro- posed global optimization algorithm, computer numerical simulation results show that our proposed approach could e?ciently and e?ectively design a minimax passband group delay nonlinear phase peak constrained FIR filter without imposing a desired phase response.
