Hybrid MVDR-LMS beamforming for Massive MIMO

Indonesian Journal of Electrical Engineering and Computer Science, 2019
<p>With the high speed of communication in LTE-5G, fast beamforming techniques need to be adopted. The training time required to form and steer the main lobes toward 5G multiple users must be short. Least-Mean-Square (LMS) training time is not suitable to work with in LTE-5G, but it has a good performance in forming multiple beams to large number
