We study energy-efficient secure link adaptation for large-scale device-to-device (D2D) underlaid cellular networks, where base stations (BSs), D2D transmitters, and eavesdroppers (Eve nodes) are distributed as independent homogeneous Poisson point processes. First, we analyze the impact of the underlaid D2D network on the secrecy performance, i.e., secrecy spectral efficiency (SE) and secrecy energy...
This chapter gives a comprehensive introduction to state‐of‐the‐art energy‐efficient communications, focusing on the physical (PHY) and medium access control (MAC) layers of wireless communication systems. The PHY layer consists of RF circuits, modulation, power control, and channel coding units, and so on and delivers data transmission as reliably as possible. The MAC layer ensures network‐wide efficient...
In this paper, we study energy-efficient power control for spectrum-sharing networks, where multiple systems of transmitting nodes share the same spectrum. In the spectrum sharing networks, reducing the transmit power of one system is always beneficial to the energy efficiencies (EEs) of the other systems. However, reducing the transmit power may not be always optimal in maximizing the EE of a system...
Diversity and transmission rate are the main performance metrics for MIMO techniques. We propose a low-complexity MIMO scheme that achieves both full diversity and full rate (FDFR) over flat fading channels when there is a sufficiently many number of transmit and receive antennas. The proposed scheme uses energy spreading transforms (EST's) to spread a symbol energy to multiple transmit antennas and...
