A Space-Time Receiver for MIMO-OFDM Ad Hoc Networks

Overview This paper proposes a receiver architecture that can demodulate multiple data streams with different frequency offsets and propagation delays in Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) ad hoc networks. The receiver performs joint synchronization and interference cancellation to separate these interfering data streams and achieve synchronization for each stream. The paper proposes a novel training-based Minimizing Mean Square Error (MMSE) algorithm to jointly obtain the frequency offsets and the equalization delays. The effects of frequency offsets and propagation delays are compensated with these estimated parameters.

Peter Cochrane's Uncommon Sense: Forget 'think different' - think 'non-linear'...

The energy output varies in direct proportion to the energy input given the losses due to frictional heating and noise. Of late I have been working with organisations that have always optimised their operations along traditional lines with singular...

Intel delays new P4 due to 'anomalies'

It represents a significant improvement in input-output capability" for PCs. Launches of complicated new processors, chipsets and other chips are subject to delays, but problems associated with Pentium 4 chips have been fairly rare.

Amazon, Microsoft in music streaming deal

Microsoft claims WM9 solves the problem of "buffering" delays related to older streaming media technology. The deal will also affect sample streams at Borders.com, CDNow.com and VirginMega.com, which outsource their e-commerce sites through Amazon.

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. The other approach sends out the signal in a single stream which reduces the complexity of the transmitter and the power it...

Qualcomm buys Flarion for $600m

Qualcomm was attracted to Flarion by its team and portfolio of intellectual property, which includes the next-generation wireless technologies OFDMA (Orthogonal Frequency Division Multiplex Access) and FLASH-OFDM, known as a type of 3.5G.

Outsourcing - life after the contract

Blowing the budget, delays and terminations are rife. One of the fundamental post-signing work streams should be to ensure that the contract is effectively managed. This constant checking, referral and change is needed to achieve the outsourcing...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
