We consider the detection of an emitter using multiple sensors. Since the emitter location is unknown, the observation depends on the range between the emitter and the sensor. We seek to optimize the detection performance by choosing the sensor locations against the least favorable distribution of the emitter location. Both centralized and distributed configurations are studied where one seeks to...
The linear minimum mean-square error (LMMSE) estimation has been shown to provide a good tradeoff between the computational requirement and estimation accuracy in nonlinear point estimation. However, the best estimator within the linear class may not be adequate to provide acceptable accuracy when dealing with a highly nonlinear problem. A generalized LMMSE (GLMMSE) estimation framework searches for...
This paper outlines a strategy for tracking evasive objects in discrete space using game theory to allocate sensor resources. One or more searchers have to allocate the effort among the discrete cells to maximize the object detection probability within a finite time horizon or minimize the expected search time to achieve the desired detection probability under a false alarm constraint. We review the...
Cooperative communication improves the QoE of source user by using relay user to retransmit its information to the destination. As a result, the improvement of QoE in source user is at the price of decaying the QoE in relay user. However, the QoE of relay user has been concerned little so far. In this paper, a new power control scheme to improve QoE of relay user in cooperative system has been proposed...
