Zhang, D.Y. (author)The performance of forward error correction codes and the respective interleaved codes for a direct-sequence code division multiple access system in a bursty land-mobile satellite channel have been evaluated in terms of throughput and delay. The FEC scheme used the Reed-Solomon and BCH codes. Interleaved codes were compared with non-interleaved...master thesis 1995

Zhang, T. (author)Conventional RF power amplifiers are normally designed for peak efficiency at maximum output power. However, for WCDMA application, the power amplifier often operates at 6-8 dB power back-off. Consequently, when the power is backed-off from its peak point, the efficiency of conventional power amplifier drops sharply. The envelope elimination and...master thesis 2009

Zhang, J. (author)The aim of this thesis project is to design and fabricate a high efficiency on chip cooling device based on the Peltier effect. Bismuth telluride (Bi2Te3) and antimony telluride (Sb2Te3) are employed to form thermocouple for their high Seebeck coefficient and high figure of merit. The models of the devices are simulated in the software program...master thesis 2010

Zhang, R. (author)This research work aims to gain understanding of the power amplifier (PA) operating as a linear PA under low power drive conditions and as a switch-mode PA in high power drive conditions both with the same Class-E load. Two approaches were taken here. Firstly, an analytical approach was developed to investigate the switching operation of...master thesis 2010

Zhang, Y. (author)Our project starts from a practical specific application of stereo vision (matching) on a robot arm, which is first building up a vision system for a robot arm to make it obtain the capability of detecting the objects 3D information on a plane. The kernel of the vision system is stereo matching. Stereo matching(correspondence) problem has been...master thesis 2010
