RSS differentialLDPC Based Differential Unitary Space-Frequency Coding for MIMO-OFDM Systems
White Paper This paper proposes a novel LDPC based differential unitary space-frequency coding (DUSFC) scheme for MIMO-OFDM systems when neither the transmitter nor the receiver has access to the channel state information (CSI). [10 Aug 2008]
Photos: The tech that holds up the net
Photo Prince Philip (left) visited the NPL in 1952 to take a look at the technology being developed, including the differential analyser he's looking at in this picture. Packet switching is one of the crucial technologies that made the internet possible. [06 Aug 2008]
XAUI: An Overview
White Paper Developed by the IEEE 802.3ae 10 Gigabit Ethernet Task Force, XAUI delivers 10 Gb/ s of data throughput using four differential signal pairs in each direction. The 10 Gigabit Attachment Unit Interface, "XAUI", is a technical innovation that... [04 Aug 2008]
Performance Modeling of Epidemic Routing
White Paper This paper develops a rigorous, unified framework based on Ordinary Differential Equations (ODEs) to study epidemic routing and its variations. These ODEs can be derived as limits of Markovian models under a natural scaling as the number of nodes... [11 Jul 2008]
Load Balancing Strategies for Parallel SAMR Algorithms
White Paper Highly resolved numerical solutions of partial differential equations are important in many areas of science and technology. Only adaptive mesh refinement methods reduce the necessary work sufficiently, allowing the calculation of realistic problems. [10 Jul 2008]
A Refinement-Tree Based Partitioning Method for Dynamic Load Balancing With Adaptively Refined Grids
White Paper The partitioning of an adaptive grid for distribution over parallel processors is considered in the context of adaptive multilevel methods for solving partial differential equations. A partitioning method based on the refinement-tree is presented. [10 Jul 2008]
Restoration Routing Using MPLS-TE
White Paper There is a need for providing such guarantees by differential treatment of the traffics for these multimedia applications. The increasing demand for multimedia applications such as VoIP and video streaming has created new challenges for network... [10 Jul 2008]
Patterns of Media Use in an Activity-Centric Collaborative Environment
White Paper Differential use of various media was observed including highly variable use of chats and surprisingly informal uses of files. This paper describes a new collaboration technology that is based on the support of lightweight, informally structured... [09 Jul 2008]
A Novel Coding Technique to Minimise the Transmission Bandwidth and Bit Error Rate in DPSK
White Paper This paper proposes a novel coding technique that aims to reduce the Transmission Bandwidth (BT) and Bit Error Rate (BER) vis-a-vis Conventional Differential Phase Shift Keying (CDPSK) in digital band pass transmission. [08 Jul 2008]

Delivering Business Agility and Service Level Management
White Paper Business Process Management is the way in which more new business applications will be created - it is the instrument that delivers the holy grail of 'Business differential'. IBM MQSeries Workflow gives customers the business agility to 'turn on a... [03 Jul 2008]
The Impact of Worker and Establishment-Level Characteristics on Male-Female Wage -Differentials: Evidence From Danish Matched Employee-Employer Data
White Paper This paper examines how the segregation of women into certain occupations, industries, establishments, and job cells impacts the male-female wage differential of full-time, salaried, private sector workers in Denmark. [03 Jul 2008]
Implementing Multi-Scale Method in GPRS
White Paper Homogenization is a classical analytical way of simplifying a multiscale problem when the fine scale physics is described by a differential operator. An "effective" operator can be derived for some classes of fine scales and problems. [03 Jul 2008]
HomePlug 1.0: Technology White Paper
White Paper Cyclic prefix and differential modulation techniques (DBPSK, DQPSK) are used to completely eliminate the need for any equalization. With the inevitable arrival of broadband access, the demand for sending digital voice, video and Internet data... [03 Jul 2008]
Sliding Multiple Phase Differential Detection of Trellis-Coded MDPSK-OFDM
White Paper In this paper, the Viterbi decoder containing new branch metrics of the squared Euclidean distance with multiple order phase differences is introduced in order to improve the bit error rate (BER) in the differential detection of the trellis-coded... [03 Jul 2008]
