Description

The aim is to provide an insight into the choice of modulation techniques employed in both current and future generation wireless networks. Analytical tools for describing information transfer and uncertainty are discussed and applied to practical data and communication systems. The key parameters that govern transmission power and bandwidth of a communication network are introduced. The unit examines both analogue and digital modulation schemes, and coherent and non-coherent detection techniques.

Elements

Information Theory Dr R. Piechocki

  • The main concepts and results of information theory (essential for communicating in the presence of accidental or deliberate noise) are introduced.
  • Information and uncertainty; entropy and information capacity.
  • Noise-free discrete communications channel; optimal coding; rate of communication over a noisy discrete communications channel.

Communications Systems Performance Dr A. Doufexi

  • Analytical techniques are developed for calculating the performance of both analogue and digital modulation schemes in order to address the important issue of cost-performance trade-off, or "Quality of Service" (QoS).
  • QoS issues in wireless networks; review of noise in wireless communications; noise in AM systems; noise and threshold effects in FM systems.
  • Design goals for digital modulation techniques; correlation and matched filter detection of data; error probability of coherent reception techniques; error probability of M-ary and orthogonal systems.
  • Performance evaluation of DS-CDMA.
