Description du livre
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.
