Available in PDF, EPUB and Kindle. Book excerpt: This book explains how the performance of modern cellular wireless networks can be evaluated by measurements and simulations With the roll-out of LTE, high data throughput is promised to be available to cellular users. In case you have ever wondered how high this throughput really is, this book is the right read for you: At first, it presents results from experimental research and simulations of the physical layer of HSDPA, WiMAX, and LTE. Next, it explains in detail how measurements on such systems need to be performed in order to achieve reproducible and repeatable results. The book further addresses how wireless links can be evaluated by means of standard-compliant link-level simulation. The major challenge in this context is their complexity when investigating complete wireless cellular networks. Consequently, it is shown how system-level simulators with a higher abstraction level can be designed such that their results still match link-level simulations. Exemplarily, the book finally presents optimizations of wireless systems over several cells.

Download or read book The Vienna LTE Advanced Simulators written by Markus Rupp and published by Springer. This book was released on 2016-03-23 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the Vienna Simulator Suite for 3rd-Generation Partnership Project (3GPP)-compatible Long Term Evolution-Advanced (LTE-A) simulators and presents applications to demonstrate their uses for describing, designing, and optimizing wireless cellular LTE-A networks. Part One addresses LTE and LTE-A link level techniques. As there has been high demand for the downlink (DL) simulator, it constitutes the central focus of the majority of the chapters. This part of the book reports on relevant highlights, including single-user (SU), multi-user (MU) and single-input-single-output (SISO) as well as multiple-input-multiple-output (MIMO) transmissions. Furthermore, it summarizes the optimal pilot pattern for high-speed communications as well as different synchronization issues. One chapter is devoted to experiments that show how the link level simulator can provide input to a testbed. This section also uses measurements to present and validate fundamental results on orthogonal frequency division multiplexing (OFDM) transmissions that are not limited to LTE-A. One chapter exclusively deals with the newest tool, the uplink (UL) link level simulator, and presents cutting-edge results. In turn, Part Two focuses on system-level simulations. From early on, system-level simulations have been in high demand, as people are naturally seeking answers when scenarios with numerous base stations and hundreds of users are investigated. This part not only explains how mathematical abstraction can be employed to speed up simulations by several hundred times without sacrificing precision, but also illustrates new theories on how to abstract large urban heterogeneous networks with indoor small cells. It also reports on advanced applications such as train and car transmissions to demonstrate the tools’ capabilities.

This book was released on 2018-09-21 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, mobile communication has been evolving rapidly, and demand for fast, secure and higher quality mobile services has increased dramatically. Thus, mobile communication service providers have been trying many different digital mobile communication standards to fulfill their customers' demands. During the last few years, major service providers have committed to a single standard known as Long Term Evolution (LTE), and within a very short period LTE has emerged as the fourth generation network choice for almost all mobile service providers. 3GPP LTE (Long Term Evolution), which is one of the latest standards for mobile communications, was proposed by a cooperation between groups of telecommunications consortium named as 3rd Generation Partnership Project to improve the UMTS (Universal Mobile Telecommunications System) mobile phone standard to meet the demands and ensure the coping with future technology evolutions. This technology describes a mobile communication standard which supports up to 300 Mbps of data transmission in downlink using the Orthogonal Frequency Division Multiplexing scheme as well as up to 75 Mbps throughput for uplink using the SC-FDMA modulation. In this dissertation, an in-depth study of LTE performance evaluation is conducted for downlink transmission under different scenarios. The focus of this book is a comprehensive analysis of LTE physical layer performance for different channel bandwidths, antenna diversities, modulation schemes and other scenarios. In addition, this study presents Bit Error Rate (BER), Block Error Rate (BLER) and throughput results based on different parameters. Overall, this book provides a comprehensive investigation of the LTE performance analysis based on detailed physical layer parameters to fill in the gap in the existing literature in LTE physical layer performance study.
