AN OVERVIEW OF MASSIVE MIMO ANTENNAS FOR 5G IN FUTURE
This research article presents an overview on Massive MIMO Systems and its original signal processing applications in future trends unclose the aspects of 5G Cellular communication. Massive MIMO is expected to be strength and support for 5G Systems. The complete antenna system is a unique combination of a multiple-input, multiple-output (MIMO) Antenna system at microwave frequencies and a millimeter (mm)wave antenna array. Massive MIMO offers enhanced broadband services more in 5GNetworks and
... in 5GNetworks and in future are expected to support a great variety of wireless services in areas like health care, smart homes and cities, manufacturing and many others. In practice, Massive MIMO has achieved a record spectral efficiency of 145bps/Hz in test bed equipment with 100 antennas at the base station. This shows an improvement of more than 20 times over 4G Systems.A novel integrated antenna solution for wireless handled devices is proposed for the existing 4G standards and upcoming 5G systems for broadband, high data rate communications. An overview of the research topic for massive MIMO Antenna array is presented. In fact with mm wave communications, a large number of antenna elements can be used to form large arrays of reasonable sizes. The standards for 5G will be set by 2020/2022. The main technologies that will be used in 5G are massive MIMO, mm wave communication, device to device communication, beam division multiple accesses etc., and we also discuss about channel estimation techniques in massive MIMO, Antenna selection in massive MIMO, capacity and energy efficiency in massive MIMO. Significant challenges that need to overcome in practical implementations. In this paper, we present an overview of important research topics related to massive MIMO Antenna arrays could lead to significant performance enhancements. In future 5G MIMO is going to be a technology which will be invisible and it will be a good area for research and implementations.
