Master Thesis in Communication Systems

Available external projects

The following list contains external thesis projects from companies which have contacted the division of Communication Systems in search of students with a suitable background in telecommunication. To apply for a project, please contact the corresponding company directly. After an agreement has been made with the company, an examiner at Communication Systems will be assigned to the project.

1. Theoretical evaluation of WCDMA receiver sensitivity on EMP chipsets
	Evaluate methods for measuring receiver sensitivity on an EMP chipset using simpler input signals and perform calculations on the corresponding WCDMA I/Q data delivered from the receiver. Company: Ericsson Location: Linköping.
2. Design and modeling of MIMO OFDM wireless base station
	Study various transmitting and receiving algorithms and methods for a wireless base station based on multiple antenna techniques. Company: PureWave Networks Location: California, USA
3. Use game theory to design cognitive networks.
	Development of protocols for cognitive wireless (ad hoc) networks that operate on secondary spectrum sharing basis in licensed spectrum. The objective is to design sensing and spectrum access policies at a cognitive terminal, for two scenarios: (i) assuming no cooperation among cognitive terminals and (ii) assuming limited cooperation among cognitive terminals. Company: Philips Research Location: Eindhoven, The Netherlands
4. Efficiency estimation of H-ARQ retransmission schemes based on sparse-graph codes
	Retransmission protocols are helpful when the transmission takes place over time-varying channels, and they are widely used in wireless communication systems. Such transmission schemes mostly use iterative channel coding techniques, owing to their close-to-capacity performance and a low decoding complexity. The goal of this study is to give an approximation of performances (i.e. average throughput and delay) of the H-ARQ retransmission protocol based on sparse-graph codes. By focusing on binary memoryless symmetric channels, we will use the scaling approach to estimate the performance of given sparse-graph code family and will combine it with the result presented by Sesia et al. for retransmission schemes. Institute: ENSEA Location: Paris, France.
5. Early Warning Collision Simulator
	Products complying with the data link named VDL Mode 4 (VDL4) have been developed during the past eight years at CNS Systems. The VDL4 is developed based on STDMA (Self Organising Time Division Multiplex Access). STDMA techniques exhibit superior safe and reliable communication of the datalink. The unique capability of addressing both broadcast and direct addressed information for time critical situations open up a wide area of business opportunities. The VDL4 data link allows an early warning collision system to be developed for helicopters by using ADS-B (Automatic dependence surveillance - Broadcast, GPS positioning) and TIS-B (Traffic information service - Broadcast, Radar positioning). However, there is limited research done based on this new technology (VDL4) where pilot awareness and alertis in focus in order to avoid collisions. Helicopter operations exhibit a significant higher frequency of incidents than regular aircraft operations. The scope of this master thesis project is to specify, design, implement and document a graphical application for creating and editing simulator scenarios. Company: CNS systems Location: Linköping.
6. Demonstration of symmetric relaying on the WARP
	This project involves the implementation and proof-of-concept demonstration of symmetric relaying in a wireless communication network. The work will be performed at Ericsson Research in Stockholm, in cooperation with LiU and KTH within the RAMCOORAN project. Salary will be paid according to a standard remuneration policy. Company: Ericsson Research (in cooperation with LiU and KTH). Location: Stockholm.
7. QoS Scheduling in HSDPA
	Investigate possible enhancements of QoS differentiation in the HSDPA scheduler. Company: Ericsson Location: Stockholm.
8. WCDMA Performance with Multi Standard Radio
	Evaluate the performance of WCDMA with Multi Standard Radio regarding network coverage, capacity and power efficiency. Company: Ericsson Location: Stockholm.

Companies often advertise available thesis projects on their web pages, typically under ``job opportunities''. Several local companies and institutes have activities relevant to the research at the division, for example, Ericsson, FOI, SECTRA. The division of Communication Systems has a large network with local industry and can usually help students find external master thesis projects. The best way of initiating such contacts is to contact the teacher in the division you feel best can assess your capabilities.

Many companies offer thesis projects in the form of internships. If you have found a project in a company and are looking for an examiner at LiU, please contact our master thesis coordinator Dr. Jonas Eriksson with a brief description (1/2 page) of the project, and a copy of your grade transcripts. The project should be related to the general area of communication systems and to the courses offered by the division or the research that we conduct.

When you write to a company or to a faculty member in Communication Systems to apply for a thesis project, please include a brief personal letter (<1 page); brief CV; and complete grade transcripts from undergraduate and M.Sc. studies. Incomplete applications will not be considered. Please use PDF file format. MS-Word attachments are usually not opened.
