Abstract: “Multiple-Input Multiple-Output (MIMO) Systems are used in wireless communication for enhancement of capacity. The main aim of this paper is to carry out investigations of MIMO system capacity and to observe the performance of MIMO system by using Waterfilling Algorithm. In which Diversity gain and spatial multiplexing gain are the two main advantages of MIMO systems that are used to study the effect of increase in bit rate with increasing the number of transmitter and receiver antennas.
