Module Aims
To enable students to appreciate and understand the architecture, key subsystems and operating principles of radio transmitters and receivers, the characteristics of radio propagation, and how noise, channel impairments and interference impact on radio systems design.
Learning Objectives
1. Knowledge and understanding
Appreciation and understanding of radio transmitter and receiver architectures,
characteristics and mechanisms of radio propagation and its impact on systems
design, the origin and design implications of impairments due to noise, interference,
non-linearity, fading or channel dispersion.
2. Discipline skills
Relate architectural diagrams to mathematical analogues, analyse and specify
radio transceiver architectures. Calculate link and noise budgets. Apply models
to predict link coverage and availability.
3. Personal transferable skills
Student will gain enhanced confidence in the formulation and execution of modelling,
analysis and design.
Prerequisite Knowledge
Honours degree in Electronic Engineering or related discipline
Assessment
100% closed book examination of 2 hours duration.
