Computationally efficient weighted least-squares design of FIR filters satisfying prescribed magnitude and phase specifications
نویسنده
چکیده
An efficient method for the design of FIR filters satisfying prescribed magnitude and phase specifications is described. The method involves formulating an objective function in a quadratic form. The filter coefficients are obtained by solving a system of linear equations which involves either a Toeplitz matrix or a Toeplitz-plus-Hankel matrix. The computational complexity associated with such systems is only O(N*).

Unified design algorithm for complex FIR and IIR filters
In this paper, a general filter design norm is proposed with the intent of producing a unified design algorithm for all types of filters— FIR, IIR and 2-D FIR with complex specifications. The Chebyshev, least squares, and constrained least squares problems become special cases because this norm uses a convex combination of the 2-norm and the Chebyshev norm. The primary benefit of this new probl...
متن کاملA weighted least square algorithm for low-delay FIR filters with piecewise variable stopbands
Variable digital filters are useful for various signal processing and communication applications where the frequency characteristics, such as fractional delays and cutoff frequencies, can be varied. In this paper, we propose a design method of variable FIR digital filters with an approximate linear phase characteristic in the passband. The proposed variable FIR filters have some large attenuati...
متن کاملTwo Novel Implementations of the Remez Multiple Exchange Algorithm for Optimum FIR Filter Design
One of the main advantages of the linear-phase FIR filters over their IIR counterparts is the fact that there exist efficient algorithms for optimizing the arbitrary-magnitude FIR filters in the minimax sense. In case of IIR filters, the design of arbitrary-magnitude filters is usually time-consuming and the convergence to the optimum solution is not always guaranteed. The most efficient method...
متن کاملQuasi-equiripple approximation of minimum phase FIR filters by updating desired response
The authors present a new numerical method for the Chebyshev approximation of minimum phase FIR digital filters. This method is based on solving a least squares (LS) problem iteratively. At each iteration, the desired response is transformed so as to have an equiripple magnitude error. This method makes it possible to design minimum phase FIR filters whose magnitude error is quasi-equiripple. U...
متن کاملA novel square-root Nyquist filter design with prescribed ISI energy
In this paper, a novel method is introduced to design Nyquist filters with prescribed inter symbol interference (ISI) energy. The computation is based on the iterative weighted least-squares optimization with a quadratic constraint. The weighted stop band and the tail energies of the Nyquist filter are minimized iteratively while the quadratic constraint prescribing the ISI energy is enforced. ...
