RSS iciDynamic Association for Load Balancing and Interference Avoidance in Multi-Cell Networks
White Paper Even in such a next-generation system, boundary users would suffer from low throughput due to severe Inter-Cell Interference (ICI) and unbalanced user distributions among cells, unless additional schemes to mitigate this problem are employed. [10 Jul 2008]
ICI Mitigation for OFDM Mobile Systems
White Paper However, for mobile applications, channel variations during one OFDM frame introduce Inter-Carrier-Interference (ICI), which degrades the performance. This paper introduces two new methods to mitigate ICI in an OFDM system with coherent channel... [03 Jul 2008]
Scattered Pilot OFDM Reception Employing Turbo Interference Cancellation for ICI Caused by Fast Fading Fluctuations
White Paper This paper proposes a scattered-pilot-OFDM reception scheme with turbo interference cancellation for alleviating inter-carrier interference (ICI) caused by the Doppler shift. The proposed receiver carries out two modes: (i) a coherent detection (CD... [03 Jul 2008]
A New OFDM Demodulation Method With Variable-Length Effective Symbol and ICI Canceller
White Paper This paper proposes a new OFDM demodulation method with a variable-length effective symbol and a multi-stage inter-carrier interference (ICI) canceller, in order to improve the bit error performance in the presence of multipaths whose excess... [03 Jul 2008]
Intercarrier Interference Self-Cancellation Scheme for OFDM Mobile Communication Systems
White Paper For orthogonal frequency-division multiplexing (OFDM) communication systems, the frequency offsets in mobile radio channels distort the orthogonality between subcarriers resulting in intercarrier interference (ICI). [03 Jul 2008]
Research of DFT-OFDM and DWT-OFDM on Different Transmission Scenarios
White Paper To combat ISI, ICI, cyclic prefix is insert between DFT OFDM symbols, and this will take up nearly 25 percent of bandwidth. To improve the bandwidth efficiency and ISI, ICI, DWT (discrete wavelet transforms) based OFDM (DWT-OFDM) is proposed. [03 Jul 2008]
Common Phase Error Correction for OFDM in Wireless Communication
White Paper In this paper the phase noise is resolved into two components, namely the Common Phase Error (CPE), which affects all the subchannels equally and the Inter Carrier Interference (ICI), which is caused by the loss of orthogonality of the subcarriers. [03 Jul 2008]
Tania Howarth
CIO Profile Described by those who know her as a "visible and inspiring IT leader", Howarth's other roles include CIO for Walkers Snack Foods between 1994 and 2003, systems manager at Sun Microsystems Europe in sales and marketing, and various project... [11 Jun 2008]
ICI Mitigation for Pilot-Aided OFDM Mobile Systems
White Paper However, for mobile applications channel time-variations in one OFDM symbol introduce intercarrier-interference (ICI) which degrades the performance. Therefore, to have an acceptable reception quality for the applications that experience high delay... [16 May 2008]
Police e-crime unit set for green light
News Paul Simmonds, former chief information security officer for ICI, added: "The response we're getting [from law enforcement] is not proportionate. The UK's proposed central e-crime police unit is close to securing the necessary government funding to... [25 Apr 2008]
ICI Cancellation Based Channel Estimation for OFDM Systems
White Paper The loss of orthogonality among subcarriers causes inter-carrier interference (ICI), which affects both channel estimation and detection of OFDM data symbols. This paper proposes a novel frequency-domain channel estimator, which mitigates the... [11 Apr 2008]
Performance Analysis of High QAM OFDM System Over Frequency Selective Time-Varying Fading Channel
White Paper The time variation of the channel during one OFDM frame destroys the orthogonality of different sub-carriers and generates power leakage among the subcarriers, known as Inter-Carrier Interference (ICI). [10 Apr 2008]
Case Study: Imperial Chemical Industries PLC - Enforcing Security SLAs of Outsourcers
White Paper ICI Group was founded in 1926 and grew into a giant international chemicals firm based in the UK. The company's 400 web addresses were targets for Internet-borne attacks on data, applications and the corporate identity. [31 Mar 2008]
A RAKE Receiver With ICI/ISI Equalizer for CCK Wireless LAN Modem
White Paper As the delay spread is larger, Inter-Symbol Interference (ISI) and Inter-Chip Interference (ICI) generated due to multipath environments are increased. To handle the increasing ISI and ICI, CCK wireless LAN modem needs ISI and ICI cancellation... [05 Dec 2007]
ADP Improves Client Service and Increases Project Management Efficiency
White Paper At ICI, a division of Automatic Data Processing, disparate project management systems left the organization without a way to reconcile the number of hours spent on a project with the amount billed. With the help of partner Immedient, ICI... [03 Dec 2007]
