Cross-relation-based frequency domain blind channel estimation for MIMO communication systems

Rathnasiri, HHS [Thesis-Full-text]

Blind channel estimation is attractive for the application of in high-speed wireless communication systems due to its high spectral efficiency. Most of the conventional blind channel identification algorithms are based ...
Developing a strategy and an open module for N-SBC to eliminate DDOS attacks from sip based NGN IP interconnections

Weerasinghe, SN [Thesis-Abstract]

The Session Initiation Protocol (SIP) is the communication protocol of the future. Used for Voice-over-IP (VoIP), Internet Multimedia Subsystem (IMS) and Internet Protocol Television (IPTV), SIP's concepts are based on ...
Development of a quality of service (QOS) policy framework for mobile broadband services in Sri Lanka

Konara, DG [Thesis-Full-text]

Development of a QoS Policy Framework for Mobile Broadband Services in Sri Lanka Quality of Service (QoS) has become an important aspect of regulation as part of industry monitoring and consumer protection objectives. The ...

An Energy efficient D2D communication model with guaranteed QoS for cloud radio access networks

Ranawaka IJ [Thesis-Abstract]

This work proposes a spectrum selection scheme and a transmit power minimization scheme for a device-to-device (D2D) network cross-laid with a cloud radio access network (CRAN). The D2D communications are allowed as an ...
EVALUATION OF EM EXPOSURE FROM WIRELESS COMMUNICATION DEVICES IN A HOUSEHOLD ENVIRONMNT

Ariyaratne, TRCO [Thesis-Abstract]

With the increasing usage of wireless devices in households, the magnitude of exposure is explored when multiple such devices are used simultaneously. Out of many wireless devices found in a typical house, the study is ...
Feasibility study on mobile number portability implementation in Sri Lanka

Hatharaliyadda, CB [Thesis-Full-text]

Mobile telephone number is considered as a great asset to a mobile telephone user. Generally subscribers are reluctant to change their mobile telephone number as it requires him to communicate about his movement to each ...
Geo based routing for border gateway protocol in ISP multi-homing environment

Thilakarathne, D [Thesis-Full-text]

BGP is the one and only protocol used by ISPs to exchange routing information between Autonomous Systems. An Autonomous System is an IP network or group of IP networks under a common administration with common routing ...
High data rate optical soliton communication systems

Athuraliya, JPDS [Thesis-Abstract]

Optical solitons are attractive at very high bit rates as linear systems are impossible at such high bit rates due to dispersion effect. In a solitor propagation system no dispersion compensation fibers are used. The pulses ...
Integration of fingerprinting and trilateration algorithms for improved indoor localization

Kodippili, NS [Thesis-Abstract]

Many useful commercial, educational, security and health-care applications of location-awareness related to navigation, tracking and detection of people and objects have been developed throughout the history. However the ...
Intelligent browser agent

Ratnayake, A.

In today's information technology era IT infra structure and solutions provide a solid base for us to carry out our day to day work. Yet the computers themselves are unable to stand on their own with complete independence. ...
INTUITIVE REASONING FOR EPISTEMIC UNCERTAINTY

Senaratne, DN [Thesis-Abstract]

Epistemic uncertainty, characterized by subjectiveness and partial availability of information, is associated with the domains of multi-sensor fusion, evidence processing, etc. Mathernatical Theory of Evidence, pioneered ...
Investigation of methods to develop a system for human psychological state detection

Ranathunga, RAMP [Thesis-Abstract]

Stress is considered a major concern of the modem world as it negatively impacts social stability by hindering performance, efficiency and overall health of people. It is the leading cause of serious life threatening ...
An Iterative capacity dimensioning scheme for an LTE advanced network under resource constraints

Chandimal KGN [Thesis-Abstract]

Since the need for high-speed broadband services is growing exponentially, legacy voice oriented networks are now becoming obsolete. Due to the unceasing demand for data, investors of mobile service providing companies are ...
K-best sphere detector based receiver for mimo non-orthogonal multiple access systems

Ranaweera NNS [Thesis-Abstract]

Non-Orthogonal Multiple Access (NOMA) is a promising radio access technology, which improves the spectrum efficiency and system throughput considerably over conventional Orthogonal Multiple Access (OMA) techniques and ...
Knowledge management framework for mobile telecommunication sector in Sri Lanka

Nadeera, J [Thesis-Full-text]

Sri Lankan mobile telecommunication industry is a fiercely competitive market space where five key mobile service companies operate. Most operators provide their services island wide; therefore the coverage footprint is ...
An MMSE-based MCI and MAI cancellation receiver for MIMO OVSF-OFCDMA systems

Kumara, NK [Thesis-Abstract]

Broadband orthogonal frequency code division multiple access (OFCDMA) with two dimensional spreading is a promising candidate for Beyond fourth Generation (B4G) networks. Since wideband channels are highly frequency-selective, ...
Modeling of multimode fiber systems

Maheswaran, M [Thesis-Abstract]

The optical communication is of great interest in developing extensive, highspeed networking infrastructures. Optical fibers provide many advantages over traditional copper cables and wireless links. Among these advantages ...
National broadband strategies for Sri Lanka
