INTRODUCTIONThe field of Cellular Mobile Communications
(CMC) is highly emerging. CMC Technologies have been in the move towards
achieving ever increasing user needs for rich multimedia services. In the past
less than three decades, enormous changes in CMC have been addressed in
technology, standard and system level. This student handout is developed to get
the students a fast but with considerable explanation of the evolution of CMC
technologies, standards and systems. A good trade-off between depth-and-breath
of any context is considered. The handout can be used for teaching and research
both senior undergraduate students and graduate students. In the first part,
fundamentals of CMC including channel propagation characteristics and modeling,
multi-path fading, channel classifications and parameters, cellular concept,
cellular system design fundamentals are addressed. Standards mainly Global
System for Mobile Communications (GSM) and GSM Evolution and Code Division
Multiple Access (CDMA) are explained in detail. In the second part (Please
refer to Technical Note on Advanced Mobile Communication), we start with a
general understanding of high data rate communications and the means to achieve
so. Advanced enabling technologies such as Multiple-input Multiple-output (MIMO),
orthogonal Frequency Division Multiplexing (OFDM), Resource scheduling, Link
adaptation, Hybrid Automatic Repeat Request (HARQ) are discussed. Third
generation (3G) standards and beyond 3G are addressed. Standards including
Wideband CDMA (WCDMA), High Speed Packet Access (HSPA), Long Term Evolution
(LTE), and LTE-Advanced (LTE-Advanced) are explained in detail. Changes in
architectures from one generation to another are explained, and their
requirements for changes are detailed. Students will get a seamless experience
throughout the handout as they read up. There are a number of problems that are
designed and collected to understand the topics discussed in the chapters. Many
of these problems are solved, and others are left for the students to exercise.
The purpose here is not to get the exercise solved, rather is to gain
understanding how to solve. Students are therefore advised to discuss with
others about the outcome of each exercise. We consider avoiding mathematical
explanation as much as possible so that students do not need much mathematical
background as prerequisite on mastering the matter. However, a good
understanding of linear algebra, Fourier analysis, signals and systems, digital
signal processing, and fundamentals of telecommunications is highly desirable.
Many of the topics are taken from industry standardization body‟s whitepapers,
IEEE publications, and renowned authors in the field. Please refer to the
Reference section for further information. Finally, we believe that this
handout will serve for understanding the fundamentals of CMC technologies,
standards and systems to the reader. Should there be any further information,
inquiry, or suggestion, please reach us with the followings.
