Abstract

The class focuses on fundamental communication-theoretic aspects of modern wireless communication systems. Main topics covered are the system-theoretic characterization of wireless channels, the principle of diversity and various diversity techniques, and information theoretic aspects of communication over fading channels like the notions of ergodic and outage capacity.

Objective

After attending this lecture, articipating in the discussion sections and working on the homeworks problem sets, students shall be able to - understand the nature of the fading mobile radio channel and its implications for the design of communication systems - analyze existing communication systems - apply the fundamental principles to new wireless communication systems, especially in the design of diversity techniques and coding schemes

Content

Wireless communications, elements of information theory, wireless channels (fading channels), ergodic and outage capacity of fading channels, coded modulation for fading channels, adaptive modulation, interleaving, error probability, error exponent, cutoff rate, multiple antenna (MIMO) systems, space-time codes, Orthogonal frequency division multiplexing (OFDM), fading multi-access and broadcast channels.
