RESEARCHER

Summary: This course provided me with fundamental and up-to-date knowledge in two of the fastest advancing technology areas. I had explored analogue and digital communications, optical communication systems, control instruments, electronic design, signal processing, and telecommunications and computer networks during my bachelor study. In the final semester, I studied on the design of optical transmitter for my thesis work, which had exposed me to the real world research environment.

Summary: Worked on wireless communication systems. Responsibilities include: providing technical solutions to the clients; expert level fault handling; participate in projects and take charge from operation side; devising new solution and implement them to adapt new requirements; implementing access control and security process as part of network infrastructure.

Summary: During two years in this school, I studied Japanese together with friends from Korea, China, Vietnam, and Russia. This experience opened my eyes, and I also got to experience interesting Japanese cultures such as kimono wearing, tea ceremony, flower arrangement and calligraphy.

Summary: The Wireless Communication programme focuses on the physical and lower layers of wireless communication. The programme features both theoretical and practical learning, as well as plenty of group assignments and presentations. During the final semester, I was involved in active research under the supervision of Associate Prof. Hidekazu MURATA for my Masters thesis work on sum rate analysis of multi-user multi-input multi-output (Μ-MIMO) in centralized and distributed antenna systems under the effects of spatial correlation.

Summary: My doctoral research focused on the dynamic clustering (over transmit and receive antennas, carriers, power) problem in large-scale MU-MIMO distributed antenna systems. To solve the dynamic clustering optimization problem and reduce the precoding complexity in the considered systems, I proposed a simple and efficient clustering scheme based on multiple orthogonal carriers with maximizing the system sum rate. For the clustering problem in the systems, I have considered several design objectives and proposed other efficient and low-complexity clustering techniques. My doctoral research focused also on the user collaboration using the WLAN or milli-meter waves for future wireless communication systems.
