In this paper, we investigate techniques for resolving the problems associated with the assumption of perfect channel information. We propose a better way of modeling the channel to track the time varying channels and estimating the channel state information efficiently using an adaptive technique. The system model will be simulated under different scenarios. Simulation results demonstrate the superiority of our solution in a time varying environment.
