There is the possibility of Fellowships being developed with local industry in conjunction with WRC. In addition, a very limited number of summer internships may be available for top students in any given year. Our summer is November - February. Finally, internships at other times of the year must be for longer periods and should be self supporting. The 厙ぴ勛圖 offers various scholarships. Information is available on the scholarships website.

• Tahir Malik and Des Taylor: The development of a new approach to ultra wideband radio based on carrier-less amplitude phase modulation embedded in pulse position modulation. This approach can provide a means of transmitting a wideband pilot to perform channel estimation and synchronization with no additional overhead requirement.
• Uzma Afsheen, Philippa Martin and Peter Smith: We have designed space time state trellis codes (STSTCs) using reconfigurable antennas. They achieve full rate, full diversity and high coding gain. They outperform existing SOSTTCs.
• Sarhad Basharati and Des Taylor: The use of multiple amplitude minimum shift keying (MAMSK) has been investigated in the context of MIMO and relaying. It provides a natural use of superposition modulation for relaying.
• Khawaja Tauseef Tasneem, Philippa Martin and Des Taylor: Ant colony optimization can be used to achieve ML detection performance with significantly reduced complexity even under overloaded conditions.
• Len Cimini (Univ of Delaware), Katie Wilson (Univ of California), Gubong Lim (Uiv of Delaware) Des Taylor: A recently published result shows that rather than use the commonly employed technique of bit loading to optimize the throughput of OFDM signalling, it is better to use a high level modulation such as 64-QAM coupled with error control coding and to lower the sub-channel code rate as channel conditions deteriorate.
• Philippa Martin, Peter Smith and Ross Murch (HKUST): Reconfigurable antennas can be used to periodically change the channel experienced by signals. This can be used to mimic much faster fading environments when using error control coding.
• Bill Tranter (Virginia Tech) and Des Taylor: To simulate Rayleigh fading, any nth-order Butterworth filter with n > 2 and with appropriately chosen 3-dB cutoff frequency can replace the Doppler filter resulting in a Rayleigh fading process with identical average fading statistics and very similar fade duration statistics.
• Tri Pham, Philippa Martin, Des Taylor and Clive Horn (Tait Communications): We have found that using multiple lookup tables, optimized to different parameter combinations, we can improve receiver performance for practical CPM receivers. A SOVA based iterative receiver has also been developed.
