A study on energy efficiency of a wireless communication system.

Wireless networks are using an increasing amount of energy to assure the quality of service as the number of high-data-rate applications increases. As a result of inadequate energy resources and eco-friendly transmission, energy-efficient communications have received significant attention. Data transmission and energy usage are tightly related in wireless communication, whereas the channel's capacity limits the data rate, and It's currently unclear how much energy a communication system require in future generations. So, in this paper, transmission power p, bandwidth B are varied to find the maximum achievable limit on Energy efficiency in future wireless devices under different scenarios. Analysis of energy efficiency as a function of channel gain and bandwidth is performed in the simulation of a single antenna system. [ABSTRACT FROM AUTHOR]
