Course overview

The course will present the underlying theory in an accessible manner, together with techniques for application of the theory to satellite and mobile communications scenarios as well as broadcasting and indoor wireless applications.

The course is usually very popular so early booking is advised.

Gaining a masters degree

This course can also form part of the MSc Electronic Engineering via short courses. The purpose of the course is to encourage those working in industry to continue with their professional development without necessitating an expensive career break.

The modular approach means that you can choose your own pace of study to fit in with your work commitments. You can elect to undertake assessment for this course should you so wish, these assessments are mainly by examination

15 credits towards the MSc in Electronic Engineering can be awarded once you have successfully completed this short course.
