Energy-Quality System Design for Wireless Communication

In the state-of-the-art wireless communication system, the energy consumed by RF front-end is always more than that of digital sections. As a result, we must minimize it to design energy-quality wireless systems. In this paper, we update our former work on RF frontend energy model and minimize the energy consumption in RF circuit by adjusting the base-band parameters, such as modulation level, data rate and signal peak-to-average ratio (PAR) etc. In the mean while, we consider the impacts of circuit thermal noise, 1/f noise, the third-order harmonic distortion and the channel flat fading, on the communication quality. Thus, the most energy efficient system parameters under certain bit error rate (BER) are determined.
