In-building power lines have often been considered as attractive media for high-speed data transmission, particularly for applications like home networking. In this paper, we develop models for power line channels based both on theoretical considerations and practical measurements. We consider power line channel frequency response and noise models in the… (More)

In a Viterbi decoder, there are two known memory organization techniques for the storage of survivor sequences from which the decoded information sequence is retrieved, namely register exchange method and traceback method. This paper extends previously known traceback approaches describes two new traceback algorithms, and compares various traceback methods… (More)

An efficient lattice-reduction (LR) aided implementation of the K-Best algorithm is proposed for the general infinite lattice detection problem, which is realized with about 80% less complexity than currently reported architectures. The saving in complexity is achieved by the introduction of an on-demand candidate generation scheme along with a distributed… (More)

This paper introduces a novel scalable pipelined VLSI architecture for a 4 4 64-QAM hard-output multiple-input–multiple-output (MIMO) detector based on K-best lattice decoders. The key contribution is a means of expanding the intermediate nodes of the search tree on-demand, rather than exhaustively, along with three types of distributed sorters operating in… (More)

The design details and test results of a field-programmable analog array (FPAA) prototype chip in 1.2-pm CMOS are presented. The analog array is based on subthreshold circuit techniques and consists of a collection of homogeneous configurable analog blocks (CAB’S) and an interconnection network. Interconnections between CAB’s and the analog functions to be… (More)

The Koetter-Vardy algorithm is an algebraic soft-decision decoder for Reed-Solomon codes which is based on the Guruswami-Sudan list decoder. There are three main steps: 1) multiplicity calculation, 2) interpolation and 3) root finding. The Koetter-Vardy algorithm seems challenging to implement due to the high cost of interpolation. Motivated by a VLSI… (More)

Efficient soft-decision decoding of Reed-Solomon codes is made possible by the Koetter-Vardy (KV) algorithm which consists of a front-end to the interpolation-based Guruswami-Sudan list decoding algorithm. This paper approaches the soft-decision Koetter-Vardy algorithm from the point of view of a communications systems designer who wants to know what… (More)

Wireless power transfer is commonly realized by means of near-field inductive coupling and is critical to many existing and emerging applications in biomedical engineering. This paper presents a closed form analytical solution for the optimum load that achieves the maximum possible power efficiency under arbitrary input impedance conditions based on the… (More)

The high spectral efficiency offered by multiple-input-multiple-output (MIMO) technology has made it the technology-of-choice in many standards like IEEE 802.16e/m (WiMAX) and the long term evolution (LTE) project and emerging 4G systems. One challenge to the widespread adoption of MIMO technology is the design of high-throughput detectors with near… (More)

Delivering milliwatts of wireless power at centimeter distances is advantageous to many existing and emerging biomedical applications. It is highly desirable to fully integrate the receiver on a single chip in standard CMOS with no additional post-processing steps or external components. This paper presents a 2 × 2.18 mm(2) on-chip wireless power transfer… (More)
