Abstract:

For the requirements of future green communication, the impacts of location and amounts for distributed antenna on the system energy efficiency are studied in wireless communication systems. Based on the analysis of energy consumption and capacity, the closed-form expression of energy efficiency is obtained, and energy-efficient networking schemes are proposed under the constraints of mobile station quality of service and total energy consumption. Simulation indicates that the distributed antenna systems with energy-efficient networking scheme can significantly reduce the total energy consumption and enhance the energy efficiency.

Key words: green communication, distributed antenna, energy efficiency, networking schemes
