Themes to which this unit belongs
  • Mobile Computing and Networks


Now that the mobile telephone has evolved into a powerful computer, the mobile dimension of computing is a vital part of Computer Science. This unit will give insights into many issues of mobile systems, including wireless communication networks, the processing of speech, music and other real-time signals, the control of bit-errors and maximising battery life. The techniques and software which underlie commonplace applications of mobile computing systems, including smart-phones, tablets, laptop computers, MP3 players and GPS satellite navigation, will be addressed.


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.


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.
