Brief Handbook Description: This is an intermediate unit of study in telecommunications following on the general concepts studied in earlier units such as Signal and Systems and leading on to more advanced units such as Digital Communication Systems. Student will learn how to critically design and evaluate digital communication systems including the elements of a digital transmission system, understand the limitations of communications channels, different analog and digital modulation schemes and reasons to use digital techniques instead of analog, and the effect of noise and interference in performance of the digital communication systems. On completion of this unit, studentss will have sufficient knowledge of the physical channel of a telecommunications network to approach the study of higher layers of the network stack.

The following topics are covered. Introduction to communications systems, random signals and stochastic process, components, signals and channels, sampling, quantization, pulse amplitude modulation (PAM), pulse code modulation (PCM), quantization noise, time division multiplexing, delta modulation. Digital communications: baseband signals, digital PAM, eye diagram, equalization, correlative coding, error probabilities in baseband digital transmission, bandpass transmission, digital amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK) and quadrature shift keying (QPSK), error probabilities in bandpass digital transmission, a case study of digital communication systems. Introduction to information theory: fundamental limits in communications, channel capacity and channel coding, signal compression.
Assumed Knowledge: Confidence in mathematical operation usually needed to handle telecommunications problems such as Fourier transform, fundamental in signals and systems theory, convolution, and similar techniques.

Laboratory: Requires Lab Preparation Report (Individual) and Lab Final Report (Group)

Lab 1: System Modeling using TIMS

Lab 2: Amplitude Modulation (AM)

Lab 3: Frequency Modulation (FM)

Lab 4: PCM Encoding and Decoding

Lab 5: Pulse-Amplitude Modulation (PAM) and Time-Division Multiplexing (TDM)

Tutorials: You will have a set of questions for each tutorial session. It is recommended that you try to solve those questions before going to the tutorial session.

A short report for each tutorial session will be collected by the tutor on the day. The content will not be marked but it will be used to check the attendance. It is however suggested that you try to write your answers in that report.

The tutor will go through questions and give you the answers. If you just come to the session without any preparation, it won’t be useful at all. Remember that it is in nature of a Communications course that the theory taught in lectures cannot guarantee solving tutorial problems. So lectures and tutorials are complementing one another, don’t miss either of them.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
Through assessment and assignments, students will become able to: 1. Exercise critical judgment in designing digital communication systems 2. Develop skills in rigorous, independent and creative thinking 3. Develop problem solving skills and account for their decisions Design (Level 3)
Developing knowledge in the area of digital communication and applying this knowledge to real situations. Understanding the merits and limitations of specific communication systems. Engineering/IT Specialisation (Level 3)
Using appropriate technology to address specific needs. Exercising critical judgement in designing digital communication systems. Developing skills in rigorous, independent and creative thinking. Developing problem solving skills and account for their decisions. Maths/Science Methods and Tools (Level 3)
Through lectures, tutorials, and labs students will become able to obtain the ability to use appropriate technology to develop communication systems addressing specific needs. Professional Conduct (Level 2)
Through labs students will become able to apply this knowledge to real situations and understand the merits and limitations of specific communication systems, by implementing real hardware and testing the results. This task is to be done in a team and requires strict time and progress control as part of their project management skill training. Project and Team Skills (Level 2)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table.
