New Hybrid Architecture for Energy Efficient and Low Complex Massive MIMO System

Massive MIMO is an important framework of 5G and the Internet of Things (IoT). Signals radiated from a 5G antenna share the complex architecture. A system is therefore needed that can minimize complexity and provides good spectral efficiency and throughput. This is achieved by reducing RF chains which is an important constraint in an energy-efficient 5G system. In this paper, a new semi-orthogonal-based scheme is proposed to formulate SINR which...
