LTE – The UMTS Long Term Evolution From Theory to Practice Stefania Sesia ST-NXP Wireless/ETSI, France Issam Toufik ST-NXP Wireless. MIMO can have benefits in spectral efficiency, data rates and robust operation but it is a complex technology with a number of variations in LTE. This book builds on the success of its predecessor, offering thesame comprehensive system-level understanding built onexplanations of the underlying theory.

In a situation where the radio waves undergo significant scattering and multipath propagation between the transmitter and receiver, a MIMO system can achieve significantly better performance than would be possible with single lte theory to practice using the same total power. For example, with suitably placed antennas, the arrangement shown in the figure could double the data throughput between the transmitter and receiver.


Lte theory to practice means of coding at the transmitter and signal processing at the receiver, a MIMO system is able to benefit from complex radio propagation environments. A number of different techniques can be applied: The same signal stream is transmitted from each antenna but with different coding applied, which enables the receiver to benefit from the diversity of the received signals.

LTE, the UMTS Long Term Evolution: From Theory to Practice by Stefania Sesia

This technique is particularly useful for system control lte theory to practice and for robust operation in poor signal conditions, such as near the edge of cells.

By applying suitable coding and signal processing these can be extracted independently at lte theory to practice receiver. The maximum number of multiplex channels that can be supported corresponds to the smaller of the number of antennas on the transmitter and receiver.

For example, the MIMO arrangement shown above could provide two independent transmission channels if the radio conditions were suitable.

This could be used to double the lte theory to practice rate available to a user or to carry two independent data streams. If feedback is available, the transmitter can modify its coding of the transmitted signals to take account of the prevailing channel characteristics, to simplify the signal processing required at the receiver and enable potentially greater performance gains.

MIMO is at its most effective when there is significant multipath propagation, such as an urban environment where signals are scattered by buildings and other objects.


Comprehensively updated with the latest changes of the LTERelease 8 specifications, including improved coverage of RadioResource Management RF aspects and performance requirements Provides detailed coverage of the new LTE Release 9 features, including: The authors not only pay special attention to the physical layer, giving insight into the fundamental concepts of OFDMA, SC-FDMA and MIMO, but also lte theory to practice the higher protocol layers and system architecture to enable lte theory to practice reader to gain an overall understanding of the system.

All the most important aspects of LTE are covered in the book.


In addition, the book surely gives something for everyone, starting from the basics and going in to the details as well. The book can be used to get familiar to mobile radio technologies with LTE used as an example. Control Plane Protocols Introduction to Downlink Lte theory to practice Layer Design.
