QRD - RLS Adaptive Filtering

The main limitation of FQRD-RLS algorithms is that they lack an explicit weight vector term. Furthermore, they do not directly provide the variables allowing for a straightforward computation of the weight vector as is the case with the conventional QRD-RLS algorithm, where a back-substitution procedure can be used to compute the coefficients. Therefore, the applications of the FQRD-RLS algorit...

Pipelined Cordic Based Qrd-rls Adaptive Filtering Using Matrix Lookahead

In this paper, the matrix lookahead transformation is developed to achieve ne-grain pipelining for Cordic based QRD-RLS adaptive ltering algorithm. Various implementation styles are proposed. They include pipelining, block processing, and incremental block processing. The proposed architectures can operate at arbitrarily high sample rates, and consist of only Givens and a few Gaussian rotations...

Iterative version of the QRD for adaptive RLS filtering

A modiied version of the QR{decomposition (QRD) is presented. It uses approximate Givens rotations instead of exact Givens rotations, i.e., a matrix entry usually annihilated with an exact rotation by an angle is only reduced by using an approximate rotation by an angle ~. The approximation of the rotations is based on the idea of CORDIC. Evaluating a CORDIC{based approximate rotation is to det...

A new QRD-based block adaptive algorithm

In this paper we present a new robust adaptive algorithm. It is derived from the standard QR Decomposition based RLS (QRDRLS) algorithm by introducing a non-orthogonal transform into the update recursion. Instead of updating an upper triangular matrix, as it is the case for the QRD-RLS, we adapt an upper triangular block diagonal matrix. The complexity of the algorithm, thus obtained, varies fr...

High - Speed Cordic Based Parallel Weight Extraction for Qrd-rls Adaptive Filtering

In this paper, a very high-speed Cordic based parallel weight extraction algorithm for QRD-RLS adaptive lter-ing is developed using the matrix lookahead technique. The algorithm is based on inverse updating and is pipelined at ne-grain level. The proposed architecture can be operated at arbitrarily high sample rates, and consists of only Givens rotations which can be mapped onto a Jacobi spe-ci...
