Low-Complexity Channel Estimation for Transmitter Diversity OFDM Systems

Overview Orthogonal Frequency Division Multiplexing (OFDM) has recently been proposed for achieving high-bit rate communication required in wireless systems. Transmitter diversity can be used with OFDM system for performance improvement in a fading environment. For these systems the receiver requires channel state information for decoding. This paper proposes a novel low complexity, frequency domain channel estimation algorithm for transmitter diversity OFDM systems. The performance of the proposed channel estimation is demonstrated by computer simulations.

TI's 'turbo Wi-Fi' - still born?

In the 802.11g standards battle, PBCC eventually lost ground to OFDM, or Orthogonal Frequency Division Multiplexing, as the modem of choice. Texas Instruments' 'turbo Wi-Fi' technology may be downshifting out of the wireless networking fast lane...

IP poised to storm the call centre

While it is true to say the vast majority of call centres still use traditional switching (aka Time Division Multiplexing or TDM) and plan to do so for the foreseeable future, IP is progressing towards a point of dominance.

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. The former method, backed by Intel, is more complex: it chops up the signal and sends it over multiple frequency bands.

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...

Complexity makes travellers miss their connection

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.
