Transmit-Antennae Space-Time Block Coding for Generalized OFDM in the Presence of Unknown Multipath

Overview Transmit antenna diversity has been exploited recently to develop high-performance space-time coders and simple maximum-likelihood decoders for transmissions over flat fading channels. Relying on block precoding, this paper develops generalized space-time coded multicarrier transceivers appropriate for wireless propagation over frequency-selective multipath channels. Multicarrier precoding maps the frequency-selective channel into a set of flat fading subchannels, whereas space-time encoding/decoding facilitates equalization and achieves performance gains by exploiting the diversity available with multiple transmit antennas.

What if... Amazon.com has bumper sales this Christmas?

Unfortunately for Amazon, it is playing the commodity game in the premier league and only a few large, pure e-tailers will survive in this space as the multi-channel big guns move in. They have done this by exploiting their brands and operational...

Peter Cochrane's Uncommon Sense: Wireless everything

We have to adopt new modes of signalling beyond carving up frequency space with individual services allocated specific channels. Another way of looking at this is to see a conversation broken into channels occupying the space currently allocated to...

The rise of new media

Trying to block such consumer demand is not the way forward. Thanks to RSS feeds and blog searching, we will begin to impose our own filters - and as the number of media consumers increases so greater diversity can be supported.

Peter Cochrane's Blog: The search for spectrum

So in contrast to the analogue world, we can reuse time, frequency and space like never before. Every time I look at the allocation of radio spectrum channels I go to a brightly coloured wall chart (see Fig 1 below) that gives the impression that...

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
