Space-Frequency Transmit Diversity in Multiband-OFDM Systems

Overview This paper investigates the suitability and performance of space-frequency block coded Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) system under UWB channel model. The employment of transmit diversity techniques based on block codes is expected to achieve enhancement in such systems since it greatly reduces the detrimental effects of multipath fading. In the proposed MB-OFDM UWB system, the space coded symbols are distributed as space-frequency block codes over neighbouring sub-carriers, therefore the space-frequency coding is independent of the time-frequency codes used in MB-OFDM system. The study shows performance improvement obtained by the proposed space-frequency coded MB-OFDM scheme.

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. The technique TI uses to boost turbo Wi-Fi's speed is known as PBCC (Packet Binary Convolutional Coding).

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. Essentially this means that all future high-speed Bluetooth devices will use UWB radio frequency technology.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
