Power Control Scheme in Very Fast Fading Wireless Communication Systems Concerning the Effect of Noise and Interference

A very efficient approach to increase the QoS and capacity of wireless communications is to control the transmit powers. The existing power control schemes are mostly designed for power adjustment in environments that the channel is varying slowly. However, when the user channels vary very fast these methods fail to properly adjust the transmit powers. For power control in such scenarios one solution is to adjust the transmit powers in order to tune the users probability of outage instead of tuning the instantaneous SINR.
