This course presents the fundamental concepts and techniques of multiple-input multiple-output (MIMO) communications over wireless communication channels. MIMO communications, which involve the use of multiple antennas at the transmitter and receiver, employ the use of signal processing techniques to enhance the reliability and capacity of communication systems without increasing the required spectral bandwidth. MIMO techniques are currently used or planned in many commercial and military communications systems. Topics include the derivation and application of the theoretical MIMO communications capacity formula; channel fading and multipath propagation; the concepts of transmit and receive space diversity; space-time block coding, with a special emphasis on Alamouti coding; space-time trellis coding; spatial multiplexing; and fundamentals of OFDM modulation and its relation to MIMO communications. Examples and applications will be presented as well as related MATLAB homework assignments.
525.616 Communication Systems Engineering; 525.614 Probability and Stochastic Processes for Engineers, or the equivalent. In addition, a working knowledge of MATLAB is required.
To develop an understanding of the concepts and mathematical techniques that underlie MIMO wireless communications.
By the end of the course, students should be able to:
Grasp the phenomenology and theory that give rise to improved reliability and the dramatic increases in data rates enabled by MIMO.
Analyze, design, and simulate MIMO communication systems.
Be familiar with practical applications of MIMO communications.

Student Assessment Criteria
|Projects (computer simulations)||30%|
Although homework is not graded, it is an important part of the course. Students are highly encouraged to complete the homework in order to gain the most from the course and to be prepared for the exams.
Since it is often difficult to develop simple closed-form solutions for the performance of MIMO communication systems, numerous graded projects will be assigned throughout the semester that involve the development of Matlab computer programs to simulate and study various aspects of MIMO. These projects are an indispensible means of gaining an indepth understanding of MIMO concepts.
Exams are generally in-class and the final exam is comprehensive.
Computer and Technical Requirements
Students are required to have a working knowledge of Matlab in order to do the projects.
