4g

4g通信技術(shù)是第四代的移動信息系統(tǒng),是在3G技術(shù)上的一次更好的改良,其相較于3G通信技術(shù)來說一個更大的優(yōu)勢,是將WLAN技術(shù)和3G通信技術(shù)進行了很好的結(jié)合,使圖像的傳輸速度更快,讓傳輸圖像的質(zhì)量和圖像看起來更加清晰。在智能通信設(shè)備中應(yīng)用4g通信技術(shù)讓用戶的上網(wǎng)速度更加迅速,速度可以高達100Mbps。[1]
  • Multicarrier+Techniques+for+4g

    At recent major international conferences on wireless communications, there have been several sessions on beyond third generation (3G) or fourth generation(4g)mobilecommunicationssystems,wheremodulation/demod- ulation and multiplexing/multiple access schemes related to multicarrier techniques have drawn a lot of attention. We often met at the conference venuesandrealizedthatnobookcoveredthebasicsofmulticarriertechniques to recent applications aiming at the 4g systems. Therefore, we decided to write a book on multicarrier techniques for 4g mobile communications systems.

  • Transmission Techniques for 4g Systems

    Fourth Generation (4g) wireless communication systems aim to allow peak data rates in the range of 1 Gbps for nomadic access and 100 Mbps for vehicular mobil- ity. 4g aims to support current and emergent multimedia services, such as mobile TV, social networks and gaming, high-definition television and video telecon- ference, multimedia messaging service, using the All-over IP concept and with improved quality of service.

  • WLANs+WPANs+towards+4g+Wireless

    This book paves the path toward fourth generation (4g) mobile communica- tion by introducing mobility in heterogeneous IP networks with both third generation (3G) and wireless local area networks (WLANs), which is seen as one of the central issues in the becoming 4g of telecommunications networks and systems. This book presents a thorough overview of 3G networks and standards and discusses interworking and handover mechanisms between WLANs and the Universal Mobile Telecommunication System (UMTS).
