Resource Allocation in Multiuser Multicarrier Wireless Systems (eBook)

This book proposes a unified algorithmic framework based on dual optimization techniques that have complexities that are linear in the number of subcarriers and users, and that achieve negligible optimality gaps in standards-based numerical simulations. Adaptive algorithms based on stochastic approximation techniques are also proposed, which are shown to achieve similar performance with even much lower complexity. All the algorithms proposed are clearly presented in concise block diagrams allowing the reader to implement these algorithms in the software of their choice. This book is an accessible reference for researchers and industry practitioners alike.

Many algorithms have already been proposed in the past to solve the problem of allocating resources in a multi-user multicarrier wireless system. Due to the difficulty of the problem, most of the previous work in this area has focused on developing suboptimal heuristics without performance guarantees. Resource Allocation in Multiuser Multicarrier Wireless Systems proposes a unified algorithmic framework based on dual optimization techniques that have complexities that are linear in the number of subcarriers and users, and that achieve negligible optimality gaps in standards-based numerical simulations. Adaptive algorithms based on stochastic approximation techniques are also proposed, which are shown to achieve similar performance with even much lower complexity.Key FeaturesWith theoretical derivations, practical algorithms, and complexity analysis this book makes an accessible reference for researchers and industry practioners alikeAll the algorithms proposed are clearly presented in concise block diagrams allowing the reader to implement these algorithms quite easily in the software of their choiceThe results of each section of the book are based on the 3GPP-LTE standard - a fourth generation cellular standard of timely importancePresents chapter on the least complex algorithms that still achieve stochastically optimal results without the need for channel distribution informationThe section on future work presents several relevant avenues for further investigation of interest to researchers in the field
