Novel identification algorithm for adaptive FIR filters

A novel adaptive step size control algorithm for adaptive filters

A novel adaptive step size control algorithm is proposed, in which the step size is approximated to the theoretically optimum value via leaky accumulators, realizing quasioprimal control. The algorithm is applicable to most of the known tap weight adaptation algorithms. Analysis yields a set of difference equations for theoretically calculating expected filter convergence, and derives residual ...

A novel multirate adaptive FIR filtering algorithm and structure

A new class of FIR ltering algorithms and VLSI architectures based on the multirate approach were recently proposed. They not only reduce the computational complexity in FIR ltering, but also retain attractive implementationrelated properties such as regularity and multiply-and-accumulate (MAC) structure. In addition, the multirate feature can be applied to low-power/high-speed VLSI implementat...

A systematic algorithm for the design of multiplierless FIR filters

A systematic algorithm is proposed for designing multiplierless finiteimpulse response (FIR) filters. This algorithm minimizes the number of adders required to implement the overall filter to meet the given amplitude criteria. The optimization is performed in two basic steps. First, a linear programming algorithm is used for determining a parameter space of the infinite-precision coefficients i...

Efficient genetic algorithm design for power-of-two FIR filters

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...
