    Performance analysis of massive MIMO for 5G wireless communication systems
    (Institute of Electrical and Electronics Engineers Inc., 2017) Islam, M.S.; Kamruzzaman, M.,; Jessy, T.,; Hassan, M.S.
    In the present age, wireless communication system has achieved a huge achievement in both efficiency and cost effectiveness. High data rate is no more a dream in present situation and this rate is increasing quite rapidly in recent past. Multiple Input Multiple Output (MIMO) is going to make an evolution in the field of wireless communication. MIMO has the capability to communicate with different antenna at a same time which are 2∗2, 3∗3, 4∗4 etc. and nowadays massive MIMO is the burning issue where hundreds to thousand antenna can communicate simultaneously which can ensure the very high data rate which is required for the 5G communication. Mm wave can play an important role to make this system more effective because the wavelength of Mm wave is very low so in that case frequency is very high which are from 30-300 GHz. Massive MIMO provides a huge channel capacity for the consumer which can definitely insure the high data rate.

    Suitable beamforming technique for 5G wireless communications
    (Institute of Electrical and Electronics Engineers Inc., 2017-01-10) Islam, M.S.,; Jessy, T.,; Hassan, M.S.,; Mondal, K.,; Rahman, T.
    5th Generation mobile network (5G) announce the next phase of mobile telecommunications standards beyond the current 4th Generation mobile communication. 5G system will achieve more than 10 Gbps which will implement within 2020. Therefore few major problems have to be solved for getting this super speed. However to achieve this super speed a high frequency wave is required to transmit data through wider bandwidth. Massive MIMO Beamforming (BF) is one of the promising technologies to develop this system and Mm wave can be used to provide higher frequency. Conventional BF is capable to provide CSI (Channel State Information) from the transmitter to the receiver but adaptive BF is not capable to do so. However adaptive BF is very much effective to change it behavior according to the required of the channel. In that case a hybrid BF technology could be very much effective to implement 5G technology which will use both analog and digital BF technology to receive the reference signal without distortion. To find out the best beamforming technique is one the major challenge to implement 5G communication and In this paper the performance of conventional, adaptive and hybrid beamforming technique has been simulated specially for 5G communication to find out the best beamforming technique.
