IRCLS algorithm for design of FIR filters with time-domain constraints
Xiaoping Lai · Journal of Shandong University · 2004
Minimax design of linear phase FIR filters with time-domain constraints is considered in this paper. The design is accomplished by solving a sequence of constrained weighted least-squares problems iteratively. During the iteration,the weighting function is updated using the envelope of the approximation error. After the process converges,a quasi-minimax solution is obtained. The method is applied to the design of FIR Nyquist filters and FIR filters with step response constraints. Simulation examples demonstrate the effectiveness of the design method.
