OFDM or Single-Carrier Block Transmissions?

Overview This paper compares two block transmission systems over frequency-selective fading channels: orthogonal frequency-division multiplexing (OFDM) versus single-carrier modulated blocks with zero padding (ZP). It first compares their peak-to-average power ratio (PAR) and the corresponding power amplifier backoff for phase-shift keying or quadrature amplitude modulation. Then it studies the effects of carrier frequency offset on their performance and throughput. It further compares the performance and complexity of uncoded and coded transmissions over random dispersive channels, including Rayleigh fading channels, as well as practical HIPERLAN/2 indoor and outdoor channels.

Intel: 'The only way is up'

Transistor gates right now are only a few atoms thick and a substantial amount of electricity slips away in transmission, a problem that will get worse as chip building blocks shrink. Transistors, the building blocks of microprocessors, may have...

Ethernet promises cheaper broadband

The Ethernet uplink from the DSLAM can be run on a spare fibre or, using a separate wave division multiplexing box, on one already in use by the ATM network. For service providers to shift models at this point - when they have invested in the ATM...

Radioactive: Bluetooth - survival of the fastest

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

Complexity makes travellers miss their connection

In the not too distant future, you will be able to add 3G Long Term Evolution (LTE), mobile WiMax, multiple in multiple out (MiMo) and orthogonal frequency division multiplexing (OFDM) to the mix. David Perry, product marketing, carrier, VoIP and...

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.
