48770 Signal Processing

6cp

Requisite(s): 48541 Signal Theory
Fields of practice: Telecommunications Engineering program
Undergraduate
Subject coordinator: Anthony Kadi

This subject aims to introduce students to the essential theory underpinning telecommunications systems. It extends the students knowledge of Fourier analysis, introduces probability theory and random processes and develops the students understanding of modulation and detection in communications systems.

After completing this subject, students are able to:

confidently represent real-life telecommunications signals in the time and frequency domain
characterise a range of modulation/demodulation techniques (amplitude, angle, pulse and digital band-pass)
understand random processes and noise in the context of communications systems, including signal detection in noise
calculate, explain and compare system performance (for example, using BER in digital systems), and
design continuous time and discrete time systems

Topics covered include: fourier analysis, probability and random variables, amplitude modulation/demodulation, angle modulation/demodulation (FM and PM), pulse modulation(PAM, PPM, PCM), baseband data transmission, basic digital modulation techniques (ASK, PSK, FSK), complex envelope representation of bandpass signals and noise, random processes, noise in analogue systems, noise in digital systems, detection, detection in noise, discrete time systems, analogue to digital conversion and time sampling, digital filtering, and signal reconstruction.

Assessment: Typically assessment for this subject involves laboratory work; Matlab investigations and a final examination.

Typical availability
