AIMS

This subject covers the fundamental design and performance issues associated with the physical and media access control of wireless networks.

INDICATIVE CONTENT

Topics include:

Wireless RF link basics (antenna characterisation, polarisation, EIRP, propagation loss);
Principles of cellular mobile radio systems (cells and frequency reuse, handover, cell splitting, sectorisation);
Characterisation and modelling of wireless channels (small scale fading including multipath channels, large scale fading);
Link budgets;
Modulation methods (linear, non-linear, single-carrier, multi-carrier OFDM);
Duplexing methods (time-division, frequency-division);
Multiple access methods (frequency-division, time-division, code-division, space-division and orthogonal-frequency-division multiple access), contention and non-contention methods;
Equalisation techniques (linear, non-linear, time-domain, frequency domain);
Lowpass Representation off Bandpass Signals and Systems;
Channel coding for error control (block codes, convolutional codes, turbo codes, LDPC), automatic repeat request (ARQ) protocols, hybrid ARQ protocols (including incremental redundancy);
Interleaving;
Diversity techniques (space diversity, frequency diversity, time diversity, multi-user diversity) and combining techniques;
Multiple antenna technologies (transmit and receive diversity, space-time block codes, beamforming, spatial multiplexing, MIMO);
Transmission of digital signals over fading channels;
Introduction to cellular mobile technologies (GSM/GPRS/EDGE, WCDMA/HSPA and LTE). Students will undertake a wireless project, such as network design, or analysis.
