摘要：
This article focuses on the problem of the centralized target state estimation with constrained communication resources. This article proposes an novel gate-corrected event-triggered mechanism. When the event-triggered condition is satisfied, the corresponding sensor only sends the quantization of the innovation to the fusion center. It reduces the data transmission amount and eases the burden of the communication system. When the event-triggered condition is not satisfied, the sensor sends the whole innovation to the fusion center. This article also derives the minimum mean square error estimation algorithm with the proposed mechanism. The algorithm's performance is also analyzed in this article. At last, its application to an optic-electric sensor network verifies the efficiency and feasibility of the proposed mechanism. Copyright © 2020 Acta Automatica Sinica. All rights reserved.
