Performance Evaluation of Channel Capacity in MIMO System
The demand for Multiple-Input Multiple-Output (MIMO) system is growing at an explosive rate with the anticipation that communication to a end user anywhere on the globe at all times will be available in the near future. Water-Filling Algorithm (WFA) is presented for MIMO Rayleigh fading environment under Channel Side Information (CSI) is known and unknown at the transmitter. The authors mainly demonstrate on efficient use of information theoretic Capacity of independently and identically distributed (i.i.d.) MIMO Rayleigh flat fading channels. However, the capacity gain is reduced if the CSI is not perfect. Assuming each antenna in Transmitter is allocated equal amount of power which maximizes capacity.
