Abstract: In this paper a new SE expression is derived which is analyzed with different linear precoding schemes. Also the effects of Pilot Reuse factor and inter cell interference is included in the simulation. The results concluded that the new scheme performs better than the existing schemes for more number of antennas. Since the proposed method shows better performance for higher number of antennas, this system can be adaptively used for Massive MIMO 5Gsystems whose basic feature is large number of transmitting antennas. The increase in SE will improve the throughput of the system which directly serves the eMBB use case of the 5G service. Massive MIMO is the emerging technology in cellular system for higher data rate communication. It employs large number of transmitting antenna at the base station which is made possible by the antenna array which can be electronically steerable and effectively used for beam forming. Spectral efficiency is the key parameter to be improved in increasing throughput. Here a new expression for Spectral efficiency is formulated and analyzed with few linear precoding and combining methods. The effects of pilot reuse factor and intercell interference is taken into account. The simulated results give a better performance improvement when the number of antennas is large which the expected outcome of this work is. This method can improve the throughput of the system and hence can be used for 5G communication.
