Efficient resource allocation in next generation multi carrier cellular networks to support multimedia traffic

Abstract

The rapid growth in mobile applications such as wireless web newlinebrowsing realtime multimedia streaming and interactive applications has newlinenecessitated the development of the nextgeneration broadband mobile newlinewireless networks High data rate transmission over wide band wireless newlinechannels is extensively limited by intersymbol interference ISI because of newlineinherent channel characteristics like multi path fading and limited band newlinewidth To contend with ISI multicarrier communication techniques which is newlinebased on modulating a large number of narrow band data streams over closely newlinespaced subcarriers has become a most accepted wireless access technique newlinetoday newline newline
