EEE6431 BROADBAND WIRELESS TECHNIQUES
Credits: 15
Course Description including Aims
This module will give an understanding of the most up to date communication techniques used in the
design and operation of broadband wireless systems based on multicarrier technology such as OFDM as
used in LTE, WiFi and 5G-NR. Specifically, the module explores the physical layer functionalities of
broadband wireless systems. The outline syllabus will include an introduction to broadband wireless
systems; the principles of radio propagation including pathloss and shadowing; narrowband and
frequency selective fading; the information capacity of wireless channels; multicarrier techniques
including OFDM; and the application of OFDM to broadband wireless communication systems.
Outline Syllabus
1. Broadband wireless system concepts;
2. Signal propagation, pathloss models and shadowing;
3. Statistical narrowband and wideband multipath fading models;

Outcome Code Supporting Statement
SM1m/SM1fl
SM4m
The module covers underpinning scientific principles and methodologies related
to broadband wireless communications by exploring topics in wireless system
design; signal propagation and multipath fading; capacity; and multicarrier
transmission techniques, in particular OFDM.
SM2m/SM2fl
The module covers underpinning mathematical and statistical principles in
broadband wireless communications through the mathematical modeling of
radio pathloss, statistical narrowband and frequency selective multipath fading;
the analysis of system SNR and the formulation of Shannon capacity; the
mathematical representation of multicarrier schemes using high order
modulation, in particular OFDM; and the mathematical representation of
broadband wireless communication systems and their performance.
SM6m/SM3fl The course builds on a range of engineering disciplines that impart a working
knowledge of signals and systems, digital communications theory, cellular
mobile principles and stochastic processes. The module also requires an
appreciation of the commercial drivers of broadband wireless systems in relation
to spectrum and standards constraints.
EA1m/EA1fl
EA2m /EA2fl
EA5m
The module aims to provide analytical skills to underpin the students’ ability to
design and analyse the performance of a broadband wireless communication
system, particularly ones based on multicarrier technology. The students
determine pathloss, characterize frequency selective channels through rms delay
spread; calculate SNRs and capacity for various channel types; and quantify the
overall performance of a broadband wireless system based on OFDM.
EA3m
EA4m
Problem solving classes involve the evaluation of a broadband wireless
transmission system, such as IEEE802.11a/g WLAN, in terms of capacity. The
system performance is assessed for different system configurations and types of
communication channels.
