RSS phasePhase Noise Suppression in OFDM Including Intercarrier Interference
White Paper In order to suppress the influence of phase noise in OFDM communications systems, the correction of the Common Phase Error (CPE) does not suffice always, especially when high data rates are required. This paper introduces a phase noise suppression... [14 Apr 2007]
Auto-ID Center Field Trial: Phase I Summary
White Paper This paper summarizes the execution, the learnings, and the results from the first phase (Phase I) of the Field Trial. The Auto-ID Center Field Trial was conceived as a test to evaluate the capabilities and practical feasibility of the Networked... [19 Jun 2004]
Phase Noise Compensation for OFDM WLAN Systems Using Superimposed Pilots
White Paper In this paper, a novel phase-error estimation technique for OFDM based WLAN system is proposed. The proposed technique utilizes superimposed (or embedded) pilots for phase-tracking within OFDM data packet. [11 Apr 2007]
Phase Noise Suppression in OFDM Using a Kalman Filter
White Paper The performance of an OFDM system can be strongly degraded by the presence of random phase noise especially if a system design targets high data rates at high carrier frequencies. Phase noise causes constellation rotation, the so called Common... [18 Apr 2007]
Managing IM for Business Advantage: Phase 2: Protecting Against IM Threats
White Paper It describes the second phase of IMlogic's four-phased approach to bringing IM under corporate control: implementing effective IM threat protection. Phase 1: Assessing IM Usage Phase 2: Protecting Against IM Threats [04 Dec 2006]
Phase Noise Considerations in Coherent Optical FMCW Reflectometry
White Paper It shows the limitations imposed on measurements of discrete reflections and of Rayleigh backscattering due to phase noise originating in the finite coherence length of the optical source. An analysis of coherent optical FMCW is presented. [24 Feb 2004]
Phase Change Recording in 12-inch TrueWORM Technology
White Paper This paper will discuss the differences between ablative and phase change recording and show that phase change is an equally, if not more, permanent recording technology. Both ablative and phase change optical recording use the same basic principal... [24 Feb 2004]
Wyse Technology Case Study: Phase 2 Telesystems, Inc.
White Paper Phase 2 Telesystems is ranked ninth in the nation for wireless resellers. Phase 2 deployed more than 80 Wyse Winterm thin clients, running on dual servers that handle between 35 and 45 clients each. Phase 2 provided outstanding customer service... [14 Jan 2005]
Managing IM for Business Advantage: Phase 3: Establishing an Effective IM Usage Policy
White Paper Download this white paper to read about the third phase of IMlogic's four-phased approach to bringing instant messaging (IM) under corporate control: establishing an effective IM usage policy. Phase 1: Assessing IM Usage [04 Dec 2006]
Two-Phase Loop: Compact Thermosyphon
White Paper It is a two-phase passive cooling loop that uses liquid as a working fluid. Power density of future microprocessors is projected to reach over 100 W/cm(superscripted 2). Shrinking system size, the need to integrate more components within limited... [24 Feb 2004]
WEEE enters final phase
News The government has announced the last phase of the implementation of the WEEE (Waste Electrical and Electronic Equipment) Directive. As of 1 July 2007, WEEE will come into force, with the aim of ensuring hardware that has reached the end of its... [25 Jul 2006]
Adaptive Nonuniform Phase-Shift-Key Modulation for Multimedia Traffic in Wireless Networks
White Paper This paper introduces adaptive signaling techniques that use nonuniform Phase-Shift-Key (PSK) modulation. The characteristics of mobile wireless communication channels fluctuate for many reasons, including movement of the radios, changes in path... [10 Nov 2006]
M-QAM OFDM and PCC-OFDM Performance in the Presence of Phase Noise
White Paper This paper addresses the issue of OFDM and PCC-OFDM systems impaired by phase noise (PN). Phase noise in OFDM causes both ICI and common phase error (CPE). PCC-OFDM is a variation of OFDM in which data is mapped onto adjacent subcarrier pairs. [26 Oct 2004]
University of Melbourne Automates Financial System in First Phase of Major IT Overhaul, Projects Significant Benefits Over Five Years
White Paper The first phase rolled out a new Oracle based financial and accounting system, enabling managers to measure performance against budget in real time, and providing labor saving automated invoice processing and reporting. [05 May 2005]
Current Status of the Phase Change Memory and Its Future
White Paper Chalcogenide based phase change memory (1) is one of the alternative memory candidates. In this review, the physics and operation of phase change memory will first be presented, followed by discussion of current status of development. [03 Apr 2008]
