This report presents the achievements and highlights of NIST¿s Information Technology Laboratory during FY2001. Following the Director¿s Foreword and the ITL overview, technical projects in ITL focus areas are described, followed by services to NIST
Performance of the Bluetooth System in Fading Dispersive Channels and Interference
A noncoherent limiter-discriminator receiver is often considered for the Bluetooth system because of its simplicity and low cost. While its performance is more than adequate for some channels, the results are significantly degraded in either an
Noise Parameter Uncertainties from Monte Carlo Simulations
We present results for uncertainties in noise-parameter measurements, obtained using a Monte Carlo simulation of the measurements. Sets of data were generated to simulate measurements on a low-noise amplifier, with given uncertainties in the underlying
Performance of the Bluetooth System in Fading Dispersive Channels and Interference

[Superseded by NIST SP 800-94, Guide to Intrusion Detection and Prevention Systems (IDPS), http://www.nist.gov/manuscript-publication-search.cfm?pub_id=50951 ] Intrusion detection systems (IDSs) are software or hardware systems that automate the process of
Bluetooth is a radio technology for Wireless Personal Area Networks operating in the 2.4 GHz ISM band. Since both Bluetooth and IEEE 802.11 devices use the same frequency band and may likely come together in a laptop or may be close together at a desktop
[Superseded by SP 800-28 Version 2 (March 2008): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=152039 ] Active content technologies allow code, in the form of a script, macro, or other kind of portable instruction representation, to execute
Techniques to Improve Bluetooth Performance in Interference Environments
Bluetooth is a radio technology for Wireless Personal Area Networks operating in the 2.4 GHz ISM band. Since both Bluetooth and IEEE 802.11 devices use the same frequency band and may likely come together in a laptop or may be close together at a desktop
NIST sponsored a public workshop for the analysis of block cipher modes of operation on August 24, 2001, in Goleta, California. This report summarizes the presentations and discussions at that workshop.
Planning Report 01-2: The Economic Impacts of NIST's Data Encryption Standard (DES) Program
[Prepared by TASC, Inc. for NIST] This report examines the evolution and economic significance of NISTs Data Encryption Standard (DES) Program. DES was developed by the National Institute of Standards and Technology (NIST, formerly the National Bureau of
I address the issue of the definition and measurement of noise figure and parameters to characterize multiport devices, particularly differential amplifiers. A parameterization in terms of the noise matrix appears to be the most practical. the noise figure
Classified Zerotree Wavelet Image Coding and Adaptive Pakcetization for Low Bit Rate Transport
In this paper, we suggest a novel robust image coding and adaptive packetization algorithm suitable for very low bit rate transport. This algorithm can be applied to any zerotree-based encoder such as the embedded zerotree wavelet coder of Shapiro and set
Needs and Research Directions in Human-Robot Interactive Systems
The advantages of using robotic systems will only be realized if non-experts in robotics are able to use the systems. This paper outlines some directions needed for research in human-robot interaction (HRI).
An Improved Voronoi-Diagram-Based Neural Net for Pattern Classification
In this brief paper, we propose a novel two-layer neural network to answer a point query in Rn which is partitioned into polyhedral regions. Such a task solves among others nearest neighbor clustering. As in previous approaches to the problem, our design
Security Self-Assessment Guide for Information Technology Systems
This ITL Bulletin summarizes Special Publication (SP) 800-26, Security Self-Assessment Guide for Information Technology Systems. Adequate security of information and the systems that process it is a fundamental management responsibility. Agency officials
