The Physical Layer Technologies in 5G Mobile Communication System
The continuously increasing demand of wireless communication impels the fast development of the next generation wireless communication technology.The fifth generation wireless mobile communication network (5G) has been proposed and is becoming a hot topic in academic and industrial field.Now, many countries or many corporations have completed the first step of 5G development which according to ITU requirements for future 5G.The 5G era is a high-speed network era of the interconnection of all things;it can load the many terminals access and high data transfer rate.However, the 5G communication technology which is scheduled to be commercialized around 2020 is still in its earlier stage.In order to solve the shortage of current radio waves resources and improve the capacity of system, two key technologies of physical layer (millimeter-wave and massive MIMO) were introduced and remarked.The best characteristics of millimeter wave technique are extremely-short wavelength and extremely-broad bandwidth.Its merits are narrow wave beam, good directivity and high antenna gain, the weakness is propagation on range of visibility.When these merits and weakness are applied to the 5G, it can solve many needs of 5G networks.
