第五代通信系统关键技术研究(论文10000字)
摘  要
    如今,人类早已进入了高速信息化时代,社会的各行各业都迅猛地发展着、科技技术的更新更是日新月异,它所带来的不仅仅是享受,更是方便与快捷。
21世纪,互联网很重要、电脑很重要,军事、商业、教育、电子商务、生活服务、教育系统、医疗系统等社会中的各行各业都离不开高效率的信息化与数字化,这是时代不断更新前行进程中必然出现的格局。
网络是个非常丰富的巨大资源宝库,效率的时代讲究的不仅是信息和数字的安全与准确,更是方便与快捷。而承载所有这些高速度、精系数、优服务业务的便是我们的通信行业与通信技术。不得不说技术是永远也没有底线的。从第一代通信系统:(频分多址(FDMA)、模拟技术)到第二代通信系统:CDMA(码分多址)、TDMA(时分多址)再到第三代通信系统:(WCDMA、CDMA2000、TD-SCDMA)再到如今比较火热的准4G(LTE)第四代通信系统:(时分双工TDD-LTE、频分双工FDD-LTE)。我们深刻的感受到了通信技术一次又一次的颠覆性、感受到了新一代通信系统的无所不能。2G普及了,3G畅快了,4G也已经大张旗鼓地来临了,如今的我们已经按耐不住欲望了,时刻都在准备着迎接第五代通信系统的来临了,而它也已经悄然地在路上了。    
所以对第五代通信系统关键技术的研究是十分重要的,也是非常具有深刻的远大意义的,更是符合时代的进步与发展的。

Research on the key technology of the fifth generation communication system
Abstract
    Today, mankind has entered the high-speed information age, the social from all walks of life science and technology rapid development, the update is change rapidly, it brings not only enjoy, is more convenient and quick.
    In twenty-first Century, the Internet is very important, the computer is very important, military, business, education, commerce, service life, education system, health system and society from all walks of life are inseparable from the efficient information and digital era, it is inevitable in the process of constantly updated on the pattern.
    The network is a very rich resources, pay attention to the efficiency of the times is not only the information and digital security and accurate, is more convenient and quick. Bearing all these high speed, precise coefficient, and service is our communication industry and communication technology. Have to say that technology is always no bottom line. From the first generation of communication system: (frequency division multiple access (FDMA), simulation technology) to the second generation communication system: CDMA (code division multiple access) and TDMA (time division multiple access) to the third generation communication system: (WCDMA, CDMA2000, TD-SCDMA) and then to now relatively hot 4G (LTE) fourth generation communication system: (time division duplex TDD-LTE, frequency division duplex FDD-LTE). We deeply feel the communication technology of subversion, once again feel the new generation communication system, be equal to anything. The popularity of 2G, the 3G 4G has put up a pageantry carefree, come on, now we have the irrepressible desire, always ready for the fifth generation communication system is coming, and it has been quietly on the road. So the research on the key technologies of the fifth generation communication system is very important, but also very great significance, it is in line with the progress and development of the times.
