Beamspace-Code Transmit Diversity for Two-Dimensional Spreading OFDM-CDM Systems

Overview This paper presents a transmit diversity scheme that allocates space-time block codes (STBC) to beamspace and spreading codes for two-dimensional spreading orthogonal frequency-division multiplexing code-division multiplexing (OFDM-CDM) downlink transmission. The STBC output symbols are beam-steered using a pair of neighboring beams directed to the user of interest. User signals transmitted from different pairs of beams, but that share the same beam, interfere with each other when decoding STBC.

Wi-Fi gets a sense of direction

Compared with radio frequencies, which pass right through walls, infrared beams can be more tightly controlled. Because the beams can be tightly controlled, Green said, it gives companies the ability to create several wireless networks within one...

Virus fears holding back IP adoption, says Avaya CEO

However, Peterson believes it will be some time before old-school TDM - time division multiplexing, or using analogue signals to transmit digital data - disappears completely. Avaya's CEO, Don Peterson, said today that worries over viruses and...

Peter Cochrane's Blog: More wireless equals more wires

Antennas that automatically beam form and steer, combined with coding and signalling systems that avoid each other and therefore minimise interference, plus a least transmit energy regime, are only the start.

Wi-fi patent threat looms after US ruling

Csiro claims its patent covers a core method for transmitting wireless signals that use orthogonal frequency division multiplexing (OFDM) modulation, which breaks signals into different parts to transmit data simultaneously over different...

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.
