Successive Projections Method, Updating Maximum Allowable Deviation, FIR Filters, Complex Chebyshev Approximation
A previous successive projections (SP) method must determinate arbitrary maximum allowable deviation. As the result, the obtained solution does not converge and/or the obtained filter does not have equiripple characteristics. We presented a design method of linear phase FIR filters by SP method recalculating maximum allowable deviation at each iteration. In this paper, we present a design method of complex chebyshev approximation for FIR filters by SP method recalculating maximum allowable deviation. Finally, we confirm the effectiveness of the proposed method through several examples.
