Course Description: MIMO Systems and Adaptive Transmission (34331600 L 006)

Course Objectives

Multiple-Input Multiple-Output (MIMO) in wireless systems refers to the use of multiple transmission and reception antennas in order to create an additional “spatial" dimension for signalling over wireless channels, beyond the conventional time-frequency dimensions. MIMO has emerged as one of the most useful and promising approaches to achieve high spectral efficiency in modern wireless systems, and various MIMO technologies have been adopted in current wireless communication standards. This course provides a profound theoretical understanding of MIMO. The target is to enable students to make use of MIMO in their own hands-on implementation projects. In addition, special emphasis is given to adaptive transmission techniques, where the choice of the MIMO scheme, including power, bit-loading, number of multiplexed data streams, precoding scheme, user selection scheduling, is adaptively chosen according to the available channel state information.
