whitepaper MIMO OFDM Receivers for Systems With IQ Imbalances2005-01-07 Institute of Electrical and Electronics Engineers
  Orthogonal frequency division multiplexing (OFDM) is a widely recognized modulation scheme for high data rate communications. However, the implementation of OFDM-based systems suffers from in-phase and quadrature-phase (IQ) imbalances in the front-end analog processing. Such imbalances are caused by the analog processing of the received radio frequency (RF) signal, and they cannot be efficiently or entirely eliminated in the analog domain. The resulting IQ distortion limits the achievable operating SNR at the receiver and, consequently, the achievable data rates. In this paper, the effect of IQ imbalances on multi-input multi-output (MIMO) OFDM systems is studied and a framework for combating such distortions through digital signal processing is developed.   
whitepaper An Open Access Wideband Multi-Antenna Wireless Testbed With Remote Control Capability2005-03-17 05:01:39 University of California, Los Angeles
  This paper introduces an open access wideband multi-antenna wireless testbed. The testbed is configured as a four transmit antenna by four receive antenna system based on software defined radio technology. It operates in the 2.4GHz ISM band and supports an RF bandwidth compatible to IEEE 802.11a/g standard. A robotic positioning system has been developed to automatically control the position and orientation of the antenna array, which makes automated testing possible and greatly reduces engineering time.   
whitepaper Adaptive MIMO OFDM Receivers: Implementation Impairments and Complexity Issues2005-03-17 04:57:46 University of California
  MIMO OFDM communications is a promising choice for future high data rate wireless systems. However, the commercial deployment of MIMO OFDM systems faces some challenges, including those arising from front-end analog implementation impairments and complex receiver structures. The impairments are caused by the analog processing of the received radio frequency (RF) signal and they cannot be efficiently nor entirely eliminated in the analog domain. This paper illustrates the effect of In-phase and Quadrature-phase (IQ) imbalances on system performance.   
whitepaper HP Case Study: KeyCorp2005-03-15 03:21:05 Hewlett-Packard
  Cleveland-based KeyCorp is one of the nation's largest bank-based financial services companies. The challenge was to build a best-in-class service management infrastructure to support the bank's increased reliance on information systems for call center, loan and mortgage services, retail and commercial banking operations. Industry and federal regulations, including Sarbanes-Oxley, require internal controls for ensuring accuracy of financial data and security of customer information. HP automated change and configuration management solutions for 18,200 desktops, 4,800 laptops, 700 UNIX servers and 2,300 Windows servers in offices, branches and call centers across 45 states.   
whitepaper m-LINX Field Service Solution for Mobile Workers2005-03-15 02:28:17 Mobile Computing
  Sheetz Inc. of Altoona, PA is one of the most watched and emulated convenience store operators in the United States. Sheetz has approximately 60 field service technicians that maintain food service equipment, gasoline dispensers, HVAC and other equipment in their stores. The m-LINX host connects to the existing dispatch computer to wirelessly send work orders to the field service technicians and to retrieve completed work details seamlessly. Through the e-Forms facility, the m-LINX system allows users to design and deploy electronic equivalents of any paper forms, such as work orders and time sheets, without programming. The system tracks technicians and maps their locations using GPS receivers on each service van.   
whitepaper Extended Systems Case Study: Bouygues Construction2005-03-15 01:40:03 Extended Systems
  Bouygues Construction, based in Guyancourt (near Paris, France), is a global construction entity, encompassing design, building, operation and maintenance of various structures and projects. As part of the "Anywhere IT" project developed for Bouygues Construction by Structis, its Corporate IT, the company sought a high-performance, easy-to-use mobile solution for managers and supervisors in the field or on the road, with data synchronization from a variety of PDAs connecting via mobile phones in GPRS or in GSM data environments and integration with the company's messaging servers. With the Extended Systems mobile groupware solution, Bouygues Construction employees now manage their e-mail, calendars, contacts, to-do lists and other PIM data via mobile handheld devices, saving time and boosting productivity.

whitepaper .NET Framework Optimizes Post-it Software Notes for
Windows XP, Pocket PC		2005-03-09 03:00:01 Microsoft
  The electronic version of 3M’s popular Post-it Notes product, which has been around since the days of Windows 95, has undergone several incarnations, the latest of which was developed using Microsoft Visual Studio .NET and the .NET Framework. This Microsoft case study explains how 3M optimized the application for Windows XP and leveraged the .NET Compact Framework to make the application more portable to mobile devices such as Pocket PCs and Smartphones.   
whitepaper Microsoft Cluster Services and Network Appliance Storage Devices: Integration of Storage2005-03-08 00:45:12 Network Appliance
  Clusters are a set of loosely coupled systems that behave as a single system. By coupling multiple independent systems to present the appearance of a single system, clients and applications can interact with the single system presented by the cluster. The cluster can then provide for system and component failure with minimal impact to the applications and clients. In many cases failures in the cluster are transparent to clients. This paper outlines the mechanisms used to create integrated highly available server clusters using Network Appliance storage targets and Microsoft Cluster Services.   
whitepaper NetApp Filers in a Microsoft Windows Environment2005-03-08 00:40:57 Network Appliance
  NetApp filers deliver highly reliable file services to Microsoft Windows clients via the Common Internet File System (CIFS) protocol. This paper describes how filers work seamlessly in the Microsoft Windows environment and enable you to effortlessly manage data by making use of standard Microsoft services and features such as the Active Directory, IntelliMirror, Volume Shadow Copy, Offline File Cache, Auditing, and Distributed File System (DFS). This paper provides a high-level view of how NetApp filers integrate in Microsoft Windows environments.
