| DESCRIPTION | This unit builds upon the knowledge gained by the students in CCE2311. Based on the theory of CCE2311, this study-unit adds practical limitations of a communication system - noise, and shows how this alters the basic theory. The overall communication system performance including the issue of information transfer is discussed. Topics to be discussed include: • Mathematical Models of Noise • Effects of Noise on AM systems • Effects of Noise on FM systems • PCM and quantization noise • Baseband Modulation in the presence of Noise • Performance of Digital (Passband) Modulation • Introduction to Information Theory • Introduction to Error Correction Coding Study-unit Aims: This unit builts upon the knowledge built by the students in CCE2311. The student learns about the effects of noise on analogue and digital communications systems, and how these are characterized and measured in practice. Information theory is introduced including source and channel coding. It also shows how in digital communications we can transmit information close to the channel capacity with arbitrarily low probability of error, and introduce error control schemes. The student learns to quantify information, and how it relates to the channel, noise and coding. Finally, the important characteristics of electromagnetic channels are covered in more detail. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to consider the practical aspects of communication systems including: • how noise is modelled mathematically. • how noise effects analogue and digital modulation. • the nature of information, source entropy and statistical source codes. • channel coding techniques for efficiency and increased S/N. • the limitations of bound copper media, bound optical media and wireless media and their effects on signal transmission. 2. Skills: By the end of the study-unit the student will be able to: • manipulate Additive White Gaussian Noise representations in the time and frequency domain. • quantify the effects of noise of analogue and digital modulation schemes both baseband and passband. • derive the S/N and probability of error performance measures for the major modulation schemes. • measure information of a source and build statistical source codes. • derive and manipulate key results in transmission lines, RF propagation and optical fibers.
