Communications

Communications research in electrical and computer engineering is cutting-edge in the fields of information and communication theory, wireless communications, and communication networks. Our researchers investigate the reliable and efficient transmission of information in many forms, such as text, image, voice, audio, and video.

At the University of Alberta, we work to develop the mathematical models of the network, signaling methods, channels, and other systems used to design communication protocols to maximize information transfer rates, minimize costs due to bandwidth and power consumption, and maximize the reliability and security of networks.
