Journal ArticleDOI
Shared time division duplexing: an approach to low-delay high-quality wireless digital speech communications
TL;DR: The authors propose a choice of low delay, high quality speech coding and digital modulation systems based on adaptive DPCM, with QDPSK or pseudo-analog transmission (skewed DPSK), for use in conjunction with the STDD multiple access protocol.
Journal ArticleDOI
Biomechanical model-based displacement estimation in micro-sensor motion capture
TL;DR: A self-contained displacement estimation method based on a human biomechanical model to track the position of walking subjects in the global coordinate system without any additional supporting infrastructures is proposed.
Journal ArticleDOI
Geo-Spatial Location Spoofing Detection for Internet of Things
TL;DR: Zhang et al. as mentioned in this paper developed a new location spoofing detection algorithm for geo-spatial tagging and location-based services in the Internet of Things (IoT), which can be implemented at the backend server without modifying existing legacy IoT systems.
Journal ArticleDOI
Hierarchical Information Fusion for Global Displacement Estimation in Microsensor Motion Capture
TL;DR: The experimental results have shown that the proposed method can accurately estimate human locomotion for the three different gait patterns with regard to the optical motion tracker.
Journal ArticleDOI
An Optimized Content-Aware Authentication Scheme for Streaming JPEG-2000 Images Over Lossy Networks
TL;DR: An optimized content-aware authentication scheme for JPEG-2000 streams over lossy networks, where a received packet is consumed only when it is both decodable and authenticated, achieves its design goal in that the rate-distortion curve of the authenticated image is very close to the R-D curve when no authentication is required.
