Wireless and Optical Communications

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 principles of spread-spectrum communications and that of spread-spectrum based code-division multiple-access (CDMA) are explored. Furthermore, the fundamentals of broadband multicarrer communications and orthogonal frequency-division multiplexing (OFDM) as well as their implementation challenges are introduced.
