In this paper, we present an FPGA implementation of a low complexity affine projection (AP) adaptive filtering algorithm based on a novel low complexity recursive filtering technique and filter update that is incorporated in dichotomous coordinate descent iterations. This adaptive algorithm is simple for finite precision implementation, requires small chip resources, and exhibits numerical stability...
In this paper, we present an FPGA implementation of a dynamically regularized recursive least squares adaptive filtering algorithm based on dichotomous coordinate descent iterations. The algorithm is simple for finite precision implementation, requires small chip resources, and exhibits numerical stability. The proposed implementation allows significant increase in the weight update rate compared...
Parallel implementation of the dichotomous coordinate descent (DCD) algorithm is proposed and analyzed. The DCD algorithm allows multiplication-free solution of the normal equations. The computational load of the algorithm is mainly due to "successful" iterations, when an iV-length auxiliary vector is updated, N being the problem size. The parallel design exploits the fact that elements...
