A Software and Hardware Evaluation of Revolutionary Turbo MIMO OFDM Schemes for 5GHz WLANs

Overview Globally, WLANs operating in the 5GHz band have been standardized by the IEEE (North America), ETSI (Europe) and ARIB (Japan). A harmonized physical layer is specified offering up to 54 Mbits/s using rate adaptive Coded Orthogonal Frequency Division Multiplexing (COFDM). Multiple Input Multiple Output (MIMO) antenna architectures coupled with Soft Input Soft Output (SISO) iterative decoding algorithms represent a revolutionary approach to the design of WLANs. In this contribution, the performance of a newly proposed iterative MIMO-OFDM architecture is explored using MIMO channel data captured in the 5GHz band. To address this situation, this paper describes the construction of a broadband 5GHz MIMO-OFDM test-bed. This advanced baseband/RF platform will be used in the future to evaluate emerging MIMO-OFDM WLAN architectures.

Strategic Vision: Giga Information Group on the economics of ecommerce

Traditionally, economic theory has regarded the economy as a whole as a vast, single value chain with raw materials and labour serving as input at one end, and consumer goods emerging as output at the other end.

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. The term 'ultra-wide band' was first coined by the US Department of Defence in 1989 which was using it for ground-penetrating radar.

Wi-Fi chipmakers get together for 300Mbps+

The new standard is likely to be based on a technology called multiple-input/multiple-output, or Mimo, which could boost throughput on wireless LANs to more than 300Mbps. Mimo works by allowing two or more distinct signals to be transmitted over...

Citywide wi-fi gets a helping hand

Menezes said Wavion solves these issues by using a version of Mimo, or multiple input and multiple output technology, which uses multiple antenna to send and receive several data streams over the same channel simultaneously.

Samsung flashes its 4G

It has also boasted hitting 1Gbps download in 2004, using SF-Spread OFDM and Mimo (multiple input multiple output) technologies. Samsung is claiming to have cracked 4G, while most of the mobile industry couldn't tell you what it is yet.

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.
