IC Design for Wireless Communication


Transmitter and Receiver circuit design for Ultra-wideband (UWB) Applications: Impulse signal generator, PPM modulator, OOK modulator, LNA, Pulse correlator, ADC.

This group is working on the integrated circuit designing for wireless communication systems, especially Ultra-Wideband (UWB) applications. UWB wireless technology can be characterized by impulse signals and very wide frequency spectrum. This new wireless system can transfer high data-rate and consume very low power compared with existing RF wireless communication systems such as 802.11x. In particular, for portable wireless devices such as PDA and GPS, UWB will bring performance improvement and longer battery life. Another benefit of using UWB technology is a lower manufacturing cost because they contain mostly digital circuit blocks and less RF components. Therefore, the systems are less complex than existing systems. Our group is dealing with Gaussian mono-pulse and Doublet type impulses. Thus, the main considered system is the pulsed UWB type. So far, some of Tx and Rx sub blocks have been designed, and system simulation and comparison with other types, CDMA or OFDM, were completed.

Digital Image Processing


This group is pursuing innovative research at the areas of digital image processing and analysis. Our research topics include edge detection, pattern recognition, algorithm development for real-time 3-D imaging, image restoration, image data fusion techniques and multimedia data processing technology and application programs. Eventually the algorithm development will be connected to the IC designs.
