Free statement of participation on completion
Exploring communications technology

This free course, Exploring communications technology, looks at some of the principles underpinning communications technology. It looks at the properties of signals and media (such as optical fibre and radio waves), error control, data compression, and the principles of 4G mobile communications, wi-fi and DSL broadband.

Course learning outcomes

After studying this course, you should be able to:

  • demonstrate an understanding of the principles of, and reasons for, carrier-wave modulation, and its application to Quadrature Amplitude Modulation
  • demonstrate an understanding of the roles of error detection and error correction, and be able to perform calculations involving check digits and coding rates
  • demonstrate an understanding of the basic techniques of perceptual coding and the reasons for their use
  • demonstrate an understanding of how the use of multiple OFDM subchannels enables efficient use of communications channels in mobile communications, broadband and wifi.
