The aim of this course is to introduce a variety of research topics in the area of wireless communications from the physical layer point of view. Participation in this module would be strongly helpful to Bachelor and Master students who consider specializing in this area.
Lectures: Student will implement a small system model under the guidance of the instructor.
On successful completion of this module, students will be able to: 1. Give mathematical descriptions of communication signal and system. 2. Characterise noise from a probabilistic standpoint. 3. Explain the principles underlying the main modulation schemes. 4. Basic understanding in the practical channel coding schemes.
The assessment procedure of this module consists by two parts.
The report may consist of 10-15 pages. The evaluation criteria of this report are listed below. 1. The report demonstrates creative work by the student and no evidence of plagiarized material. 2. Contains sufficiently good knowledge of the project topic clearly and concisely. 3. Sources are appropriately cited. 4. Demonstrates critical understanding of findings/application. 5. Provide more detail derivation, clear presentation of ideas and justifiable assumptions.
Note: A very good report shows critical thinking, a new application of the knowledge, or higher level thinking skills—not only reiterating the existed knowledge.
2. Oral Presentation
The student is required to present his/her work orally once the report is submitted. The presentation may take around 10-15 min.
'The student is awarded pass/fail based on the assessment criteria outlined above 1 and 2.'
- Basic understanding in probability theory and programming skills in MATLAB or C would be beneficial.
- A student will be required to do a small research project on the topic of his/her choice. He/she will also be required to write and present a research report.
The project assignments are in the following areas (but not limited to)
- Study of Wireless Relay System Model
Wireless communication technology is widely used in mobile access services. Invention of new techniques has bought a notable improvement in the field of wireless communication. These improvements in turn have revolutionized data rate, device size, communication reliability and network connectivity. Cooperative communication in a wireless network is more popular because of its flexibility and user-friendly nature. Single relay model is one of the simplest models of cooperative communication. This aim of this project is to study the relay system model in wireless cooperative communications.
- Performance Analysis of Relay Protocols
In cooperative wireless communication, a source transmits a message to a destination with the assistance of a relay. The relay listens to the source’s transmission and may retransmit the message to the destination. By combining the source and relay transmissions, and depending on the relaying protocol used, the destination can achieve extra coding gain against practical channel obstacles without the use of an antenna array at any terminal. In this project, the student will look in to the different relay protocols from the physical layer point of view.
- Study of Wireless Relay Channels
In wireless communications, fading is deviation of the attenuation that a carrier-modulated telecommunication signal experiences over certain propagation media. The fading may vary with time, geographical position and/or radio frequency, and is often modelled as a random process. A fading channel is a communication channel that experiences fading. In wireless systems, fading may either be due to multipath propagation, referred to as multipath induce. This short study will investigate the characteristics of basic wireless fading channels.
