Multipath error is the most important unavoidable source of error contributing to the User Equivalent Range Error (UERE). It is difficult to model, but it is very necessary for us to describe signal multipath performance of Global Navigation Satellite System (GNSS). Multipath error envelope based on noncoherent early-late code tracking loop has become a common approach to describe the effects of specular...
Aimed at the challenges existing in current network performability research, this paper proposes an analysis architecture for network performability research, in which FMEA of the network, the availability model of the equipment, the topology analysis, the performance evaluation and the design of performability verification platform are integrated into together. This architecture assures accuracy...
This paper presents a self-injection-locked (SIL) sensor array for cancelling the effects of random body movement on the detection of vital signs. To achieve this goal, a subject is seated between two SIL sensors to measure rates of respiration and heartbeat using the Doppler shift, and the effects of random movements by the subject are cancelled by wireless mutual injection locking (MIL) of the two...
Sound source localization is an important function in robot audition. The existing works perform sound source localization using static microphone arrays. This work proposes a framework that simultaneously localizes the mobile robot and multiple sound sources using a microphone array on the robot. First, an eigenstructure-based generalized cross correlation method for estimating time delays between...
