Divya SINGH, Aasheesh SHUKLA Manifold Optimization with MMSE Hybrid Precoder for Mm-Wave Massive MIMO Communication
ABSTRACT: Hybrid Precoding (HP) major key aspects of millimeter-wave in wireless communication is used to enhance the energy and spectrum efficiency and also to reduce the system complexity, cost, and path losses. The sub-connected structure of HP is used further to minimize hardware complexity and power consumption. In this article, an effective HP algorithm is developed for the maximization of spectral efficiency as well as for the minimization of bit error rate in the Mm-Wave massive MIMO system. This proposed algorithm makes use of Manifold optimization and MMSE criterion to increase spectral and energy efficiency and also to reduce hardware complexity. Simulation results show the achievement of significant efficiency and cost via the use of the proposed algorithm over conventional ones.KEYWORDS: Mm-Wave; Manifold optimization; MIMO; Hybrid precoding; Minimum mean square error.Read full text (pdf)
