Book Description
Moreover, we propose a fast algorithm with linear complexity for computing the optimal WF level and perform simulations to illustrate the effectiveness of the proposed algorithm. Next, we investigate the trade-off between spectral efficiency (SE) and EE, which are the two important design criteria of future wireless systems. We introduce an optimization problem to maximize the SE of a multi-user OFDM system with a constraint on its minimum EE. Exploiting this formulation, we analyze the trade-off between SE and EE as a function of various parameters, such as circuit power, power amplifier (PA) efficiency, number of users, number of subcarriers and channel power gain. Attention is then paid to energy-aware resource allocation in a quality-of-service (QoS)-constrained DL mixed-traffic multi-user OFDM system.

Book Description
This book introduces the sources and historic collection campaigns of resource allocation in wireless communication systems. The unique characteristics of MIMO-OFDMA systems are thoroughly studied and summarized. Remarks on resource allocation and spectrum sharing are also presented, which demonstrate the great value of resource allocation techniques, but also introduce distinct challenges of resource allocation in MIMO-OFDMA systems. Novel resource allocation techniques for OFDMA Systems are surveyed from various applications (e.g., for unicast, or multicast with Guaranteed BER and Rate, subcarrier and power allocation with various detectors, low-complexity energyefficient resource allocation, etc.) in this book. Due to the high mobility and low latency requirements of 5G wireless communications, this book discusses how to deal with the imperfect CSI. It also discusses how to deal with e.g., throughput maximization, outage probabilities maximization and guarantee, energy efficiency, physical-layer security issues with feedback channel capacity constraints, in order to characterize and understand the applications of practical scenes. This book will target professionals & researchers working in the fields of Wireless Communications and Networking, Resource Allocation and Transmissions. Advanced-level students in electrical engineering and computer science will also find this book useful as a secondary textbook.
