White Paper Moreover, cultural issues, increased frequency of change, and regulatory compliance requirements add layers of complexity to IT change management processes. Overview: Change management is one of today's most pivotal IT management disciplines. [12 Dec 2007]
Complexity of Wavelength Assignment in Optical Network Optimization
White Paper This paper studies the complexity of a spectrum of design problems for optical networks in order to carry a set of demands. Under Wavelength Division Multiplexing (WDM) technology, demands sharing a common fiber are transported on distinct... [08 Dec 2006]
Complexity holding IT back, say CIOs
News CIOs believe too much complexity and not enough innovation are holding back IT departments. Speaking on a panel at the BusinessWeek CIO Discussion Evening in London last night, Brian Jones, CIO of Allied Domecq, said: "Complexity is the enemy of... [19 May 2005]
Efficient MIMO Equalization for Downlink Multi-Code CDMA: Complexity Optimization and Comparative Study
White Paper Hermitian optimization is proposed to further reduce the complexity. A comparative study in both performance and complexity with the Conjugate-Gradient (CG) algorithm is then presented. This paper presents an efficient LMMSE chip equalizer to... [11 Oct 2005]
Complexity, Fragmentation, Uncertainty and Emergence in CRM
White Paper In the authors' view, the real reasons for this difficulty can be grouped into three categories: dynamic complexity, fragmentation and uncertainty. Definitions of CRM may be suspect. Companies often think of CRM as equivalent to technology. [10 Jan 2007]
CIO Jury: Complexity is the enemy
News Complexity caused by business change and rapid technology developments is still one of the main battlegrounds for CIOs, according to UK tech chiefs. Analyst Gartner's annual CIO survey this week revealed that almost two-thirds of IT budgets are... [14 Feb 2007]
Complexity Reduction Techniques for DSP-based Multi-Channel Echo Canceller Systems
White Paper This paper describes the use of two techniques to reduce the complexity of a First, the MCEC system complexity can be reduced by efficient utilization of DSP architectural features to achieve an increased number channels per DSP. [24 Feb 2004]
Complexity Plagues Reliable Software Development
White Paper Complexity is the major obstacle to developing reliable, fail-safe software for electronic and weapons systems in the defense and military sectors. The challenge to software reliability over the next 20 years will not be speed, cost or performance... [06 May 2004]
Complexity makes travellers miss their connection
Comment In fact, the biggest challenge for business travellers is not finding a network connection but the complexity arising from having multiple modems, logons and payment methods. This approach helps keep a lid on uncontrolled costs and reduces the... [12 Jun 2008]
Complexity Comparison of Iterative Channel Estimation, Equalization and Decoding for GSM Receivers
White Paper This paper presents the trade off between complexity and performance of 4 different types of GSM receiver: Conventional training sequence channel estimation receiver, iterative channel estimation feedback from equalizer, iterative channel... [15 Nov 2005]
Low Complexity System-on-Chip Architectures of Parallel-Residue-Compensation in CDMA Systems
White Paper The commonality is extracted to avoid the direct Interference Cancellation and reduce the algorithm complexity from O (K2N) to O (KN). This paper proposes a novel multi-stage Parallel-Residue-Compensation (PRC) receiver architecture for enhanced... [11 Oct 2005]
Stratified Round Robin: A Low Complexity Packet Scheduler With Bandwidth Fairness and Bounded Delay
White Paper This paper proposes a novel packet scheduler called Stratified Round Robin, which has low complexity, and is amenable to a simple hardware implementation. Fair queuing is a well-studied problem in modern computer networks. [01 May 2004]
