Improved spectral and energy efficiency are two key requirements for the fifth generation (5G) wireless communication systems. The inefficiency and non-linearity of traditional power amplifiers (PA) pose significant challenges to meet these requirements, especially for multicarrier modulation signals (MCM) with high peak to average power ratio (PAPR). In this paper, we study methods to improve the...
In this article, we provide an overview of the 5GETLA radio interface proposal for low latency dense small-cell networks. We discuss the new physical layer parametrization and frame design to support high energy and spectral efficiency in wireless small-cell communications and compare the main parameters with another recent physical layer design proposed for 5G centimeter wave communications. The...
Prolonging the battery life of mobile terminals (MTs) is critical for mobile users, especially for the smartphone users to enjoy the high data rate services offered by the future wireless networks. A collaborative mobile cloud (CMC), which consists of several MTs offers one potential solution for reducing the energy consumption at the terminal side in the downlink. In addition, as RF signal can carry...
