We developed a high speed wireless LAN prototype in the 5 GHz band. Maximum transmission rate of the developed WLAN system is 324 Mbit/sec using 6 multi-channels of 802.11a. We propose a closed-loop link adaptation scheme to improve MAC efficiency. The proposed scheme inserts MCS (Modulation and Coding Scheme) feedback information into Data frame and ACK frame. The MCS is calculated based on the estimated...
In this paper, we propose a novel vibrometric imaging technique for two-dimensional and real-time vibration measurement. Our system consists of two major components: 1) projector of moving stripes to encode vibration amplitude and phase into time-varying intensity of light, 2) correlation image sensor (CIS) to select a single frequency component and decode its amplitude and phase distribution in a...
