Mobile Communications

Goals

The goal of MOBCOM, at least as I teach it, is to provide a fundamental understanding of mobile communication systems. The course will seek to describe the key aspects of channel characteristics/modeling, of communication techniques, and to describe the application of these techniques in wireless communication systems. The course will cover recent research developments, such as opportunistic communications, basic aspects of MIMO communications, and OFDMA. Specific topics will include basic properties of multipath fading, diversity techniques, multiple access and interference management, fundamental capacity exposition and opportunistic communications

Contents

Physical channel modeling, input/output channel models, time and frequency channel coherence (Doppler spread, coherence time, delay spread and coherence bandwidth), statistical channel modeling. Detection in fading channels, degrees of freedom, effects of channel uncertainty, diversity techniques (time diversity, antenna diversity, frequency diversity, space-time codes).

OFDM, channel estimation. Capacity of AWGN and fading wireless channels, multi-user capacity and opportunistic communications, uplink/downlink AWGN channel, uplink/downlink fading channel, multiuser diversity, multi-node networks.

Time Wednesday, 1:30pm - 4:45pm
Office Hours Wednesday 10am - 12am , Room 329

Course Pre-requisites:

An understanding of probability theory, random processes, transform theory, and digital communications is useful.

Suggested Text Book:

Fundamentals of Wireless Communication, by D. Tse and P. Viswanath, Cambridge University Press, May 2005.

A leading textbook providing a unified view of wireless communications. Some lectures will follow the outline of the text, placing emphasis on the first seven chapters. Different topics will be drawn from different sources, from the suggested books described below.

Grading:

Part Date Percentage
Final exam Early February 55%
Midterm exam November 20%
MATLAB sessions 15%
Homeworks 10%

Exams:

The Final Exam will be two hours long, and it will be comprehensive. During the final exam, all notes corresponding to this class (MOBCOM Fall 2015, at Eurecom) are allowed.

The midterm exam will be smaller (1-1.5 hours), and it allow for 2 crib sheets only.
