Pilot Reuse Pattern Optimization in Massive MIMO for Spectral Efficiency Enhancement using GA

  Atul Kumar Mishra,  Prof. Saurabh Gaur

The area data throughput of wireless network becomes an important parameter which needs to be improved to manage the growing wireless data traffic requirement. MIMO techniques have already proven to improve the spectral efficiency hence improvement in area data throughput. In this direction, the concept of Massive MIMO technologyhas shown significant improvements in area throughput by increasing the spectral efficiency (bit/s/Hz/cell) with same bandwidth and basestations density. In spite of the big advantage of massive MIMO system, it suffers by the problem of pilot contamination which increases the effective interference. In this paper, the concept of pilot reuse is shown for reducing the pilot contamination. Further the reuse pattern is optimized by GA for enhancing the spectral efficiency.
