Stability of FFLS-based Diffusion Adaptive Filter Under Cooperative Excitation Condition
Stability of FFLS-based Diffusion Adaptive Filter Under Cooperative Excitation Condition
In this paper, we consider the distributed filtering problem over sensor networks such that all sensors cooperatively track unknown time-varying parameters by using local information. A distributed forgetting factor least squares (FFLS) algorithm is proposed by minimizing a local cost function formulated as a linear combination of accumulative estimation error. …
