Multi-user MIMO offers enormous favorable circumstances over customary point-to-point MIMO. It works with modest single-radio wire terminals, a rich dissipating environment is not required, and asset assignment is disentangled in light of the fact that each dynamic terminal uses constantly recurrence containers. Notwithstanding, multi-client MIMO, as initially imagined, with generally parallel quantities of administration reception apparatuses and terminals and recurrence division duplex operation, is not a versatile innovation. Massive MIMO makes a total separation with current practice using a huge abundance of administration radio wires over dynamic terminals and time-division duplex operation. We consider the inter user interference in uplink transmission and downlink transmission in Massive MIMO system with non-ideal Hardware. The interference variance can actually increase briskly, conspicuously when used pilot contamination evolved scale linearity. So far, many researches have inscribed the effect of pilot contamination (PC) on path estimation. Here numerical analysis of inter user interference and pilot contamination on multi cell system with non-ideal Hardware is designed.
