Abstract
Mobile WiMAX is appropriate basis for service provisioning in broadband wireless networks. The purpose of the project is modelling and simulation of existing and new multi-antenna techniques presented in the specifications for mobile WiMAX system, including transmit diversity, beamforming and spatial multiplexing. Deployment of advanced multi-antenna solutions enables considerable system improvement, resulting in higher performance, smaller number of sites, higher power and spectral efficiency and lower price. Important aim of the project is also modelling and development of software tools for simulations in order to assess suitability and quality of multi-antenna techniques. Some of the simulation results we shall compare with the data, obtained from the measurements of the signal power in the WiMAX pilot network, built by Telsima in co-operation with Iskratel and Telekom Slovenije, which also financially support our project.
Significance for science
Research project includes innovation elements, which are important from the scientific point of view, what is proved by the publication of the articles in national and international journals. particularly important are two patent applications, submitted to US PTO, related to the field of self-organizing networks including WiMAX pico base stations. Scientific contributions are reached particularly in the following topics: - development of radio channel model which enables appropriate design of radio network, - development of software toll for WiMAx signal coverage calculation, - selection of new procedures to assess the quality of radio channel, - investigation and analysis of new coding and modulation techniques for MIMO systems, - design of iterative decoding techniques in MIMO systems, - investigation of new technique for mobile user localization in mesh network, - development of new procedures for self-organizing base station parameter adaptation to the envirionment in the WiMAX network.
Significance for the country
With network simulation tools, used and developed in the project, we can design the network architecture more efficiently. By simulations we can evaluate the performance of broadband wireless networks under various traffic loads The research project is forming the technological basis for the implementation of new platform for broadband wireless access, which is efficient, adaptive, competitive and significantly contribute to higher GDP, faster economical growth and advanced society in Slovenia. The project results are particularly useful for company Telsima, and its spin-off company 4G Neuron, which is developing and producing base stations for the WiMAX system and is selling them at home as well as in the global market, particularly in India. Slovenian service providers and operators may benefit from the project results. Software tools which were developed and upgraded during the project are useful for design and performance evaluation of wireless telecommunications networks and service provision.
