Module Title Communication Systems (LI) School of Engineering Elec, Elec & Sys Engineering 04 13812 Dr SF Quigley Intermediate Level 10 Semester 1 Available in Electronic & Electrical Engineering, Electronic Engineering, Electronic & Software Engineering, Computer & Communication Systems Engineering, Communication Systems Engineering Lecture-20 hours Tutorial-2 hours Practical Classes and workshops-9 hours Guided independent study-69 hours Total: 100 hours None INTRODUCTION TO COMMUNICATION SYSTEMS Wired transmission lines Wireless communications INFORMATION THEORY Shannon's theory Channel capacity Effect of noise on digital signals. DIGITAL BASEBAND TRANSMISSION Fourier transforms: Revision Baseband signals and spectra Random digital waveform, PSD Baseband noise. Probability of error. Sampling and Quantisation;Nyquist rate Quantisation noise FILTERS Chebyshev passive LC filters Synthesis from tables Frequency and magnitude scaling PASSBAND SIGNALS AND SPECTRA Analogue AM, FM waveforms and their spectra Digital (binary) waveforms: ASK, PSK, FSK ,and their spectra Complex envelopes. By the end of the module students should be able to: Be able to compare transmission line types (twisted pair, coaxial, fibre optics etc) and recommend the optimal types for particular applications; Understand the concepts of land mobile (handheld radio, cellular) and satellite communications and perform simple calculations; Explain and perform calculations on matched filtering, sampling and quantisation; Derive the design formulae for Chebyshev filters, and design them from tables; Deduce filter parameters from a given circuit, and design simple filters; Derive equations defining modulated signals, given the baseband signals, and vice versa. Explain the relationship between modulated signals and their baseband counterparts, both in the time and frequency domains. 13812-22 : Communication Systems CW1 : Coursework (15%) 13812-23 : Communication Systems CW2 : Coursework (15%) 13812-24 : Communication Systems CW3 : Coursework (50%) 13812-25 : Communication Sys Canvas Quiz : Class Test (20%) Assessments: One 2-hour formal written examination (80%) to be held during the University's examination period (May/June) plus assessment of laboratory work (20%).
