Mujthaba Waseem K, Dr. Vidushisarma


Adaptive modulation and adaptive beam forming methods are the hottest research areas. Many of the researchers worked on these two techniques to apply on MIMO antenna systems. The general problems exist in these methods are uncertainty in steering vector, angle of arrival problem, if the required signal is available slow convergence problem exist, channel interference, and etc. In this paper we conduct a detailed survey on different adaptive beam forming and adaptive modulations techniques used in MIMO antenna base wireless communication environment. In this survey we analyzed the different problems addressed by different research scholars and we tabled the survey report on adaptive beam forming, adaptive modulation, and MIMO antenna system
