Introduction

Scope of Module This module will address the problem of transmitting a signal through a noisy channel. We will look at both analog and digital signals.

Topics

• Analog signals
  • Transmission of analog bandpass signals.
  • Synchronisation
  • analog modulation techniques
    • AM, DSBSC, SSBSC, VSB, FM and phase modulation.
  • Noise in analog modulation systems.
• Digital Representation of Analog Signals.
• Review of probability theory for communications.
• Baseband digital communications
  • binary bandwidth limited signals and inter-symbol interference
  • noise and threshold detection
  • adaptive equalisation
• Band pass digital systems:
  • binary PSK and FSK, QPSK.
• Introductory information theory
  • entropy
  • discrete memoryless channel
  • source coding theorem
  • channel coding

(The above ratios should be consistent with the values recorded by the Registry, but the latter should be regarded as definitive. Let me know of any inconsistency so that I can update this page.)

The CA element will comprise up to two assignments. Both will involve simulation of signals and channels and are currently in preparation. We will use Matlab/Simulink to perform the simulations. If you are not familiar with Simulink, you should start practising now.

As the name suggests, this title does not cover analog communications.
