Use of a Peak-to-Average Power Reduction Technique in HIPERLAN2 and Its Performance in a Fading Channel

Overview A technique that uses clipping has been recently proposed to reduce the peak-to-average- power ratio (PAPR) in orthogonal frequency divisional multiplexing (OFDM) signals. The technique uses a discrete Fourier transform (DFT) based filter to reduce out-of-band (OOB) power after the interpolated baseband OFDM signal is clipped. In this paper, the technique is applied to HIPERLAN2 to reduce the PAPR of the transmitted signals. Like many other OFDM systems, HIPERLAN2 has a number of unused subcarriers.

Peter Cochrane's Uncommon Sense: Wireless everything

We can create complex digital signals that occupy a broad swath of frequency space and still filter them out at the receiver. This column was typed on an Apple G4 laptop and transmitted to silicon.com via a wireless LAN using a spread spectrum signal.

Radioactive: Bluetooth - survival of the fastest

The first work was the development of what was then called impulse radio, baseband or carrier-free communications back in the 1960s. The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB.

Peter Cochrane's Blog: The search for spectrum

It could be hard to work out the details but I don't see why unused broadcast radio and TV channels cannot be used for WLAN applications. Fig 3: Most of the radio spectrum remains unallocated and unused!

Wi-fi patent threat looms after US ruling

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.
