The rapid pace of development in wireless technology has put substantial requirements on various system parameters e.g. handling large number of users, huge data transfers, efficient time usage, higher transmission rates and improves transmission quality are required. Numerous papers have been published in wireless channel estimations techniques like pilot allocation schemes, lest square estimation, minimum mean square estimation. In this paper we are focusing on OFDM (Orthogonal Frequency Division Multiplexing) and the estimation of channel in an OFDM system by allocation of Pilots (known as reference signals).
