An introduction to technical details related to the Physical Layer of the LTE standard with MATLAB(r)The LTE (Long Term Evolution) and LTE-Advanced are among the latest mobile communications standards, designed to realize the dream of a truly global, fast, all-IP-based, secure broadband mobile access technology.
This book examines the Physical Layer (PHY) of the LTE standards by incorporating three conceptual elements: an overview of the theory behind key enabling technologies; a concise discussion regarding standard specifications; and the MATLAB(r) algorithms needed to simulate the standard.
The use of MATLAB(r), a widely used technical computing language, is one of the distinguishing features of this book. Through a series of MATLAB(r) programs, the author explores each of the enabling technologies, pedagogically synthesizes an LTE PHY system model, and evaluates system performance at each stage. Following this step-by-step process, readers will achieve deeper understanding of LTE concepts and specifications through simulations.
Key Features:
* Accessible, intuitive, and progressive; one of the few books to focus primarily on the modeling, simulation, and implementation of the LTE PHY standard
* Includes case studies and testbenches in MATLAB(r), which build knowledge gradually and incrementally until a functional specification for the LTE PHY is attained
* Accompanying Web site includes all MATLAB(r) programs, together with PowerPoint slides and other illustrative examples
