Recently, the capacity of the broadcast channel with multiple antennas is investigated. Various space-time (ST) processing techniques to adapt channel conditions are utilized to increase capacity. Precoding becomes vital to deal with interferers and cooperation problems efficiently. ST codes will be investigated in conjunction with precoding. We aim to investigate channel adaptive ST coding and precoding techniques to achieve the maximum capacity with practical quality of service requirements. Although the capacity is extensively investigated, implementation methods are relatively less investigated. This project is to fill the cap between implementation (ST coding and precoding methods as outcomes) and theory (capacity analysis).Read moreRead less

Smart antennas can facilitate accommodation of an increasing demand for bandwidth and quality in wireless communications by directing the antenna beam towards the desired user, while suppressing signals coming from interferers. The beam forming processor can adapt to changes in channel propagation conditions as well as movements of the user or interferers. Many algorithms for controlling smart antennas have been proposed, and usually there is a trade-off between complexity and performance. We aim to find a suitable compromise to implement smart antennas for broadband wireless access systems and to apply smart antenna technology to increase the range of ultra-wideband communications.Read moreRead less

A Three-Dimensional Ultra-Wideband Microwave Method Based On Multiple Antennas For Early Detection Of Breast Cancer. Breast cancer is the most common cause of cancer-related death among women in Australia. In 2003, it killed 2,713 women in Australia and approximately 400,000 worldwide. Despite significant advances, current breast screening methods still suffer from several limitations. They may miss as many as 15% of cancers. Inconclusive results are common, leading to invasive, expensive and pa ....A Three-Dimensional Ultra-Wideband Microwave Method Based On Multiple Antennas For Early Detection Of Breast Cancer. Breast cancer is the most common cause of cancer-related death among women in Australia. In 2003, it killed 2,713 women in Australia and approximately 400,000 worldwide. Despite significant advances, current breast screening methods still suffer from several limitations. They may miss as many as 15% of cancers. Inconclusive results are common, leading to invasive, expensive and painful follow-up tests such as biopsies. About 75% of such biopsies are found to be negative, and this is a major deterrent for women in undertaking breast screening. The proposed project contributes to the cause of finding a more reliable breast cancer detection method, and hence, saving thousands of lives each year.Read moreRead less
