Abstract

Recently, the QR decomposition (QRD) method has been extensively used in the recursive least squares (RLS) adaptive filtering problems. And the least squares lattice (LSL) algorithm has been rederived based on the QRD method. On the other hand, in order to increase the throughput in the general RLS, a triangular systolic array for block processing based on the QRD method with Householder transformations has been derived. In this paper, we derive an adaptive FIR lattice filter structure for block processing based on QRD with Householder transformations.
