Adaptive Beamforming towards 5G systems

MIMO has been the undisputed candidate for wireless communications. It provides high diversity order and increased data-rate. Beamforming is a technique that helps to exploit the channel and minimize the inter-user interference among the cells. This article mainly discusses about the basics of dynamic approach of beamforming formation which will help in real-time wireless communications systems to achieve higher data-rate with higher number of users in future wireless systems. This article provides the basic context of beamforming in current systems followed by a case study. In the later part, it briefly explains about co-ordination of beamformers and its advantages and disadvantages over present systems.
