It is caused by the reuse of similar pilot signals by various users present in the cellular network required for channel estimation. In this paper, a cluster-based pilot reuse technique has been proposed where users present in different cluster reuse the same pilot signal. The technique is inspired from co-channel frequency reuse and allocates similar pilots to users which are at a considerable distance from each other. The simulation results presented substantiate the profficiency of the technique in eliminating the resisting effects of pilot contamination on system sum-rate in inter-cluster network.
