This paper is to improve channel estimation accuracy in OFDM system because channel state information is required for signal detection at receiver and its accuracy affects the overall performance of system and it is essential to improve the channel estimation for more reliable communications. OFDM system was chosen in this paper because it has been widely used today due to its high data rate, channel capacity and its adequate performance in frequency selective fading channels.
