COMP28512 Mobile Systems syllabus 2019-2020
OverviewNow 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.
Commonplace examples of mobile computing systems: - mobile phones; - MP3 players; - laptop computers; - PDAs; - GPS satellite navigation.
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.
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.
10, plus a few lab support lectures
Feedback methodsMarks and feedback on the three laborartory tasks, the presentation and the report will be communicated via Blackboard.
Feedback on previous examinations is available via the School, and feedback on this year's examination will be published in due course.
