Basic theories and key technologies in next generation networks

T he next generation network is a high-speed broadband network based on the packets, which offers unrestricted access by users to different service providers. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users. The wireless communication network is an important part of the next generation network. With the rapid development of wireless networks and smart-phone techniques, more and more image, video and other high data rate services are expected to be deployed, which lead to great interests to devise new innovative wireless technologies. There have been some breakthroughs in multiple access, advanced waveform technologies combined with advances in coding and modulation, algorithms and architecture.
