Module overview
This module introduces both the wireless and optical propagation environments, the modelling of the corresponding channels as well as their implications on the design and architecture of wireless and optical communications systems. The basic principles of digital transmission in both wireless and optical communications are considered, including the techniques of enhancing the reliability of wireless and optical systems. The fundamental multiple-access and multiplexing concepts as well as the principles and challenges of broadband communications are also covered.
