Abstract: ABSTRACT METHODS TO ESTIMATE CHANNEL USING A SINGLE PILOT IN A WIRELESS COMMUNICATION SYSTEM The disclosed methodology provides a methodology to estimate channel using a single pilot symbol in the wireless communication. According to an embodiment, the method includes receiving, by a node, a plurality of modulated data symbols, and a pilot symbol. Further, the method includes determining, by the node, at least one first centroid point corresponding to the plurality of modulated data symbols. Further, the method includes determining, by the node, a distance between the pilot symbol and each of the at least one first centroid point. Further, the method includes selecting, by the node, a second centroid point from the at least one first centroid point, wherein the second centroid point is the first centroid point with a minimum distance from the pilot symbol. Further, the method includes estimating, by the node, the channel based on the second centroid point and at least one information about the pilot symbol.
