Abstract
Applications for wireless networks are growing despite the challenge of the energy costs. Further, the number of users is increasing within the basic wireless facilities which are depending on the energy efficient systems. Apparently, users need minimum energy cost influenced with the efficient design of wireless network such as multiple-input, multiple-output (MIMO). In this research, I have considered some energy-saving ways for massive MIMO wireless system, which will be able to integrate with the next generation technology. The process of energy saving should be utilized between the source and destination of massive MIMO wireless network. Best and efficient processing will maximize the total energy efficiency (EE). To tackle the dilemma of supporting EE, MIMO with Pn-manifold or massive MIMO with feedback will be used as a new method. Manifolds are types of nonlinear multi-dimensional mathematics applied in MIMO system, which allow us to enhance the efficiency of the communication channel. Despite the less energy consumption used in the MIMO design, manifolds techniques are even better in terms of complexity and cost. In the proposed approach, feedback channel and computation of quantization influenced with Pn and Stiefel manifold, provide better resolution and spectrum during the communication than the existing systems. Therefore, this method will be useful to enhance the total EE.
