• Artificial Intelligence BSc (Hons)

Aims

Computing is becoming increasingly mobile. This unit will give insights into the issues of mobile systems, covering mobile communications, real-time signals such as speech, video and music, codecs, and maximising battery life.

Learning Outcomes

A student completing this course should:

Appreciate the issues that differentiate mobile from tethered systems.
Have a working knowledge of speech, music and video codecs.
Understand the basics of wireless communication.
Appreciate the holistic nature of power-efficient system design.

Assessment of Learning outcomes

All learning outcomes will probably be assessed incrementally in the laboratory

Contribution to Programme Learning Outcomes

TBD

Syllabus

Mobile systems

Commonplace examples of mobile computing systems: - mobile phones; - MP3 players; - laptop computers; - PDAs; - GPS satellite navigation.

Real-time signals

Analogue and digital signals; - time and frequency domain representations; - sampling, aliasing, quantization; - companding; - real-time computation.

Coding, decoding and compression

GSM speech coding; - MP3 music, JPEG image and MPEG video coding & decoding; - error correcting codes; - communications coding schemes.

Mobile communication

Transmitting real-time information over wireless networks; - principles of cellular and ad-hoc networks; - Coding of multimedia signals - to increase the capacity of radio channels; - to minimise the effect of transmission errors.

Maximising battery life

May be addressed at many levels including: - chip design; - signal coding and processing; - medium access control; - transmit power control.
