4g

4g通信技术是第四代的移动信息系统,是在3G技术上的一次更好的改良,其相较于3G通信技术来说一个更大的优势,是将WLAN技术和3G通信技术进行了很好的结合,使图像的传输速度更快,让传输图像的质量和图像看起来更加清晰。在智能通信设备中应用4g通信技术让用户的上网速度更加迅速,速度可以高达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).
