Proposal of Adaptive Downlink Modulation Using OFDM and MC-CDMA for Future Mobile Communications System

Overview To meet the strong demand for broadband multimedia services by both nomadic and mobile users, it is important to increase the bit rate of future mobile communications systems. To enhance system capacity, novel technologies or new concepts for improving bandwidth efficiency are indispensable. In this paper, an adaptive downlink modulation using OFDM and MC-CDMA is presented for maximizing the system capacity and actualizing QoS (Quality of Service) control of future mobile communications.

VoIP takes hold with small businesses

However, Vonage and other internet telephony services rely on customers' broadband connections, most of which do not provide high quality of service (QoS) for voice and the number of simultaneous callers are limited by the upload capacity.

Peter Cochrane's Blog: NGNs - real or imaginary?

Repeater spacing went from 2km to 40km or more, capacity projections went off the scale, power demands dropped and everything, including QoS, improved beyond recognition. While traffic density improved again, the really big win was in signal...

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?
