A survey on multiple access technologies beyond fourth generation wireless communication system

The future of mobile wireless communication networks will include existing 3rd generation, 4th generation 5th generation,6th generation (with very high data rates Quality of Service (QoS) and service applications) and 7th generation (with space roaming). Mobile and wireless networks have made tremendous growth in the last fifteen years. The rapid improvement of the mobile generations was for the purpose of supporting as many mobile devices as possible that could benefit the users at anytime and anywhere in terms of common practical applications such as internet access, video-ondemand, video conferencing system and many more applications. This paper is focused on the specifications of future generations and latest technologies to be used in future wireless mobile communication networks like MIMO, OFDM, OFDMA, Massive MIMO, LTE, LTE-A.
