Vehicle monitoring systems have recently become a urgent necessity. This paper describes a high accuracy differential positioning vehicle terminal based on BeiDou Navigation System, comprised of a BeiDou differential positioning module, a GPRS communication module, and a S3C 2440A control module. This vehicle terminal can perform real-time data acquisition and storage, and the information can be displayed...
This letter proposes a paradigm shift in wireless security from preventing conventional eavesdropping attacks to a new legitimate surveillance objective by studying how a legitimate monitor (e.g., a government agency) efficiently eavesdrops a suspicious wireless communication link. The suspicious transmitter controls its communication rate over Rayleigh fading channels to maintain a target outage...
