Efficient Detection of Zero-Padded OFDM Signals With Large Blocks

Overview This paper presents a frequency-domain receiver for ZP-OFDM schemes (Zero-Padded Orthogonal Frequency Division Multiplexing) where the duration of the channel impulse response is a significant fraction of the duration of the OFDM block. The proposed receiver has a relatively low complexity, allowing an FFT-based (Fast Fourier Transform) implementation. The proposed receiver is suitable to ZP-OFDM systems with very large blocks (hundreds or even thousands of subcarriers), since it does not requires the inversion or the multiplication of large matrixes.

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...

Siemens claims gigabit wireless breakthrough

The demonstration at its Munich laboratories on Tuesday reached speeds of 1Gbps, twenty times faster than 802.11g, thanks to a combination of new OFDM techniques and multi-in, multi-out (MIMO) antenna technology.

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.

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.
