Amanda Parkin, marketing manager at approved design and build consultant to the NHS for integrated theatres and digital video communications, OR Networks, explains how, with the help of the company and its specialist equipment, Northumbrian surgeons successfully established a two-way audio/video link to their counterparts at a hospital in the foothills of Mount Kilimanjaro to enable them to tra...

On the Full - Rate Linear Complexity 2 2 Space - Time Block Code : Application in Keyhole Channels

In this paper, a new full rate, full diversity 2 2 STBC with linear complexity in the receiver is introduced for keyhole channels, where the rank-deficiency of the channel matrix degrades system performance. This code is optimized based on the known criteria for these types of the channels. Simulation results demonstrate that the proposed code outperforms some of the well-recognized STBCs when ...
