Alireza Sheikh

Doktorand at Electrical Engineering, Kommunikationssystem, informationsteori och antenner, Communication Systems

Alireza Sheikh is a PhD student in the Communication Systems research group, and part of FORCE (Fiber Optic Communication Research Centre). His PhD studies are focused in finding the most power hungry aspects of communication in fiber optic channels and trying to minimize the consumed power to have an energy efficient communication with using digital communication, signal processing and coding theory methods.
