Digital Communications 4 (U00367)

? Credit Points : 10 ? SCQF Level : 10 ? Acronym : EEL-4-ELDCO

The aim of this course is to provide students with a thorough understanding of how information theory relates to the design of digital communications systems and to provide the knowledge and skills to perform design calculations on these systems. Students will use standard mathematical methods to model and analyse digital communication systems and predict performance metrics such as received SNR and expected bit error ratio.

Summary of Intended Learning Outcomes

After successful completion of this course a student will be able to:
- perform bit error rate calculations with the use of decision criteria and noise levels;
- explain the principles behind various speech coding schemes and calculate SNR for n bit coder;
- manipulate the entropy principle to design efficient block and convolutional coding techniques to correct received errors;
- compare and contrast ASK, FSK, PSK IF coding schemes in terms of occupied bandwidth, complexity etc. and extend these into QPSK, MPSK, QAM for improved spectral efficiency;
- perform error rate calculations given formulae;
- derive receiver noise performance, free space link path loss and perform receiver noise predictions on terrestial and satellite receiver systems;
- explain the basic concepts of personal mobile communications, GSM European TDMA and CDMA systems;
- describe in terms of block diagrams, telephony multiplex systems using PDH and SDH and perform efficiency calculations on these systems.
