Abstract: In a base station the number of transmitting antenna number is in fixed numbers. In this paper a we propose a new antenna number optimization using the analysis of several parameters on Per Cell Spectral Efficiency. Additionally a new SE expression is derived from the new proposed precoding scheme PZFn and is compared with different existing linear precoding schemes . The analysis of SE parameters with respect to the different existingprecoding schemes conclude that the proposed linear scheme PZFn performs better than the existing schemes. Also it observed that when the antenna number is approaching towards 1000 the results shows a better performance. This supports 5G is standard which is expected serve with 1000 transmitting antenna. In this paper Per Cell Spectral Efficiency is analyzed with parameters like Per Cell SE for fixed number of Users, pilot reuse factor β ,achievable SE per UE, SNIR, Coherence Block Length and finally with hardware impairments. The simulated results shows a common pattern that the antenna number is proportional to the transmitted data. This results can be used by the base station which is equipped with antenna array having several antenna arrays. The number of antenna units used for transmission is decided from the simulated parameters.
