Techies plugging in and tuning out
News Meanwhile, a devil-may-care 13 per cent not only choose to crank up their favourite track as they work through helpdesk logs but also blast it out over speakers so their colleagues have to listen too. [09 May 2007]
Reduced Complexity Blind Layered Space-Time Equalization for MIMO OFDM Systems
White Paper Blind Source Separation (BSS) combined with a Vertical Bell Laboratories Layered Space-Time (V-BLAST) scheme is used in a small portion of subcarriers to perform blind signal detection and channel estimation iteratively. [18 Apr 2007]
ICEE Serves Up Better Customer Service and Efficiency
White Paper The ICEE Company is a leading provider of popular beverages such as the ICEE, Slush, Smoothie, Arctic Blast, as well as other snack foods found in consumer venues and outlets throughout North America and Mexico. [16 Apr 2007]
Blind Layered Space-Time Equalization for MIMO OFDM Systems
White Paper This paper proposes a novel blind receiver for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems, where Blind Source Separation (BSS) and V-BLAST are combined to perform layered space-time equalization... [14 Apr 2007]
Channel Estimation for D-BLAST OFDM Systems
White Paper This paper applies D-BLAST in Orthogonal Frequency Division Multiplexing (OFDM) systems and addresses the issue of channel estimation. Different from other MIMO-OFDM, where symbols at all tones are always available for decision-directed channel... [13 Apr 2007]
Approaching MIMO-OFDM Capacity With Closed-Loop V-BLAST
White Paper This paper presents a closed-loop extension of the Vertical Bell Labs Layered Space-Time (V-BLAST) architecture for which the transmit power and rate assignments for each transmit antenna at different OFDM tones are optimized at the receiver and... [11 Apr 2007]
Performance of Space-Frequency Techniques Over Measured Channels in MIMO-OFDM Systems
White Paper The paper investigates Space-Frequency Trellis Coded Modulations (SFTCM) along with a number of BLAST detection algorithms: ML, Successive Interference Cancellation (original BLAST); linear ZF; ZF-ML hybrid. [11 Apr 2007]
Joint Data Detection and Channel Estimation for OFDM Systems
White Paper Avoiding a computationally prohibitive exhaustive search, it solves the data detectors using Sphere Decoding (SD) and V-BLAST and provides simple adaptations of the SD algorithm. The paper develops new blind and semi-blind data detectors and... [11 Apr 2007]
Blasting Linux Code
White Paper This paper evaluates, from a practitioner's point of view, the utility of the popular software model checker Blast for revealing errors in Linux kernel code. The conducted case studies show that, while Blast's abstraction and refinement techniques... [04 Apr 2007]

Steel Manufacturer Improves Blast Furnace Performance
White Paper As SIDMAR prepared to reline its blast furnace - an endeavor undertaken about every 15 years - the steel manufacturer decided it needed a solution for monitoring and operating its production processes in real time. [08 Feb 2007]
Space web video chat lined up
News The first cosmic chinwag via the internet will blast off next week, giving Earthlings the chance to chat to an astronaut orbiting 400km above our planet. The European Space Agency (ESA) and German ISP T-Online will beam up the live space video chat... [23 Nov 2006]
Record breaking Xmas on the cards
News A spokesman for e-tail consultant Blast Radius, which commissioned the research, said the study shows investment by online retailers focuses on "what they care about most: securing the sale". Royal Mail expects to deliver around 100 million... [22 Nov 2006]
Web smut labelling plan still on cards
News Civil liberties advocates blast the labelling approach as overly sweeping. The US Department of Justice has stepped up its defence of a proposal to imprison website operators who don't label pages containing sexually explicit material. [19 Sep 2006]
