Content

Propagation effects and sources of multipath components in radio channels;
Propagation models: free space, plane earth, diffraction models, empirical models;
Multipath modeling: Fading with time and fading with frequency;
Statistical Models: Wide Sense Stationary Uncorrelating Scattering model;
Coherent time and coherent bandwidth, Level crossing, Fade rate duration;
Channel Measurement systems: CW, periodic pulse, PRBS, Chirp
Channel parameter and functions: impulse response, Power Delay Profile, Average Delay, Delay Speed, Coherent bandwidth, frequency selective fading, time selective fading, and scattering function;
Small scale and large-scale statistics;
Detection in noise: matched filter and correlation detector;
Bandpass data transmission: ASK, FSK and PSK, DPSK and non-coherent FSK;
Error rate calculation;
Mitigation of Multipath effects: diversity reception techniques, multiple antenna techniques and the RAKE receiver;
Spread spectrum modulation;
Introduction to the cellular concept: Common air interface, frequency reuse, channel assignment strategies, handoff strategies, interference and system capacity;

Learning Outcomes

Subject-specific Knowledge:

An understanding of the basic propagation effects in radio channels;
An appreciation of multipath effects;
An understanding of narrowband and wideband channel models;
To be familiar with channel measurement techniques and the analysis of data for the extraction of the relevant channel parameters;

Subject-specific Skills:

Key Skills:

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

Teaching by lectures and tutorials which are supported by a laboratory programme.
Written examinations are appropriate because of the wide range of in-depth, analytical material that is covered.
Theoretical and laboratory-based coursework contribute a formative element to the module and aid the acquisition of subject-specific and key skills.
