An appropriate adaption of the decision boundaries of the well-known signal space detector (SSD) yields a detector that whitens the input noise in the detector forward path. This new detector, called a whitening signal space detector (WSSD), offers h

A sequential key equation solver algorithm for Reed-Solomon codes is presented. This work is motivated by the need for Error Correction Coding (ECC) On-the-Fly (OTF) in high data rate storage devices. In these applications the ECC encoder/decoder cir

We present a data puncturing (DP) type-II hybrid ARQ protocol with low-density parity-check (LDPC) codes. Incremental redundancy is created from punctured versions of the original data using the same encoder/decoder hardware. Thus, parts of the initi

In this paper homogeneous systolic solutions to overdetermined systems of linear equations are described. The least-squares problem (LSP) can be solved on two-dimensional mesh-connected or hexagonal arrays. Simple partitioning schemes can be applied

In this paper, we present a novel constant rate (CR) type-II hybrid ARQ protocol with low-density parity-check (LDPC) codes. The decoder architecture always operates at the highest code rate, thus efficiently exploiting the decoder hardware. Incremen

We present-a low-complexity soft detection and soft decoding magnetic disk drive read channel with a modified soft-output signal space detector (S/sup 3/D) which uses 3D-110 equalization and an error/erasure decoding Reed Solomon (RS) code. The detec

An algorithm is presented that requires only multiplications, additions, and a single division for the orthogonal solution of a system of linear equations. For that purpose the QR-decomposition of an extended system matrix, called the orthogonal Fadd

One- and two-dimensional processor arrays for the orthogonal solution of systems of linear equations are presented. The arrays execute the orthogonal Faddeeva algorithm, and each processor cell is able to carry out a square-root and division-free Giv

An algorithm is presented for sorting n/sup 2/ elements on a two-dimensional systolic processor array. It is proved that this algorithm requires O(nlog n) steps in the worst case. The state of the whole processor array recurs every eight steps, so no
