Saving Energy for Wireless Transmission: An Important Revelation from Shannon Formula

Abstract: The reduction of power consumption is important for wireless communications and networks. To develop the energy-saving technologies for future wireless transmissions and networks, this paper presents two basic study points: 1) The multiple events are merged into a single event; 2) the high-order mode is changed to the low-order mode. For this reason, we seek that multiple events in wireless transmission links are fused into a single event from Shannon formulas. We also analyze the relationship between the information modulation and the error correction, and give a fusion structure of error-corrected modulation. The energy-saving performance of the error-corrected modulation method is further analyzed through comparison with the traditional methods of modulation plus error correction. The results of numerical analysis demonstrate the wireless energy saving methods for wireless systems based on Shannon formulas are the achievable efficient schemes.
