An Adaptive Method for Multi-User MIMO Power Controlled Systems
(0) For achieving high performance at wireless networks, we can use Multiple-Input Multiple-Output systems (MIMO). By using channel information at Base Station or Mobile Station we can remove or mitigate inter-user interference at multi-user MIMO systems. For designing of Mu-MIMO system we must attend to inter-user interference problem which can reduce performance and capacity of systems. capacity optimization, maximizing throughput under power restriction, power control problems or power minimization under satisfying minimum quality of service are some sample of such problem. None of them has closed form unless by applying some restriction at them. In this paper, we solve some of them by using block diagonalization and successive optimization methods with equal & adaptive power allocation methods.
