| CHANNEL MODELLING FOR WIRELESS COMMUNICATION | ETI085 |
Higher education credits: 6.
Grading scale: TH.
Level: A
(Second level).
Language of instruction: The course will be given in English.
Compulsory for: MWIR1.
Optional for: C4, C4ks, D4, D4ks, E4, E4ks, MSOC2.
Course coordinator: Fredrik Tufvesson, fredrik.tufvesson@eit.lth.se, Inst för elektro- och informationsteknik.
Recommended prerequisits: ETI031 Radio, ETT051 Digital Communications.
The course might be cancelled if the numer of applicants is less than 8.
Assessment: Exam (oral or written, 5 hours) and approved assignment reports. The performance assessment is based on the exam, which might be oral or written. To pass the course the assignment reports also have to be approved. The two assignments are to be solved in pairs of two students as independent work. These assignments include planning of measurements, performing the measurements, analysing the data and writing a report. Submission of all assignments is a requirement for participation in the exam.

Aim
The aim is to give a comprehensive view of the properties of the wireless channel. This includes an understanding of the underlying physical propagation mechanisms, measurements of channel properties and methods for modelling these.
Knowledge and understanding
For a passing grade the student must
- have an understanding of the properties of the wireless channel and its interaction with the system
- have a comprehension of the physical propagation mechanisms and thereby being able to evaluate propagation conditions for a certain scenario
- have a comprehension of measurements of radio channel properties and methods for modelling these properties.
Skills and abilities
For a passing grade the student must
- be able to analyse and describe the properties of the radio channel and its interaction with the system, and from this be capable to select appropriate system parameters
- be able to propose and evaluate methods for using the radio channel in the most appropriate way.
Judgement and approach
For a passing grade the student must
- have a comprehensive view of how the radio channel interacts with other system blocks in a radio system
- feel confident in the ability to understand, analyse and describe the properties of the radio channel in order to use it in the most efficient manner.
Contents
The course connects different areas of knowledge within, e.g., radio, digital communication, probability theory, stochastic processes, wave propagation and mathematics. The course covers the following topics:
- Propagation Mechanisms - Free space propagation, reflection and transmission, diffraction, scattering on rough surfaces, wave guiding
- Statistical Description of Wireless Channels - The time-invariant two-path model, time-variant two-path model, small-scale fading without line-of-sight, small-scale fading with line-of-sight, Doppler spectra, level crossing rate and random FM, large-scale fading
- Wideband Channel Characterization - Narrowband vs. wideband systems, system-theoretic description of propagation channels, the WSSUS model, description methods for time dispersion, description methods for angular dispersion
- Channel Models - Narrowband models, wideband models, spatial models, deterministic models, models for ultra wideband channels
- Channel Sounding - Time-domain methods, frequency-domain methods, generalizations, spatially resolved methods
- Antenna aspects in wireless systems - Requirements for antennas in mobile radio, antennas for mobile stations, antennas for base stations, aspects of multiple antenna systems.
