This unit covers the basics of digital and analogue information transfer over wired and wireless links. Topics include baseband and bandpass (M-FSK, M-PSK, M-QAM) modulation formats and associated error control coding, pulse shaping, symbol timing and carrier recovery techniques, together with bandpass analogue modulation techniques.
Fundamentals Communications:
Overview of communication systems. Factors affecting system capacity: bandwidth, noise, distortion. Quantitative metrics for Communications. Shannon's capacity theorem and bandwidth efficiency.
Baseband Digital Modulation:
PAM binary and multi-level signalling, Implications of inter-symbol interference and pulse shaping, Nyquist filters, matched filters, root raised cosine filters. Generation and interpretation of eye diagrams.
Bandpass Digital Modulation:
Introduction to the generation, detection, spectra and performance of digital modulation methods: Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), Minimum Shift Keying (MSK), Phase Shift Keying (PSK), Phase Shift Keying (DPSK). Binary and Multilevel modulation schemes. Coherent, non-coherent and differentially coherent detection methods.
Laboratory:
Modem design exercise
Error Control: Automatic Repeat Request and Forward Error Correction as strategies for error control. The pros and cons of each and the implications of error control in the context of Shannon Capacity.
On completion of this unit, students should be able to:
