New feedback structure and its fusion arithmetic for distributed detection

The paper proposes new multi-step feedback scheme about the way in which the fusion centre feeds back to itself in distributed detection systems. The multi-step feedback scheme can unify former single-step feedback circumstance. And the detection performance and convergence rate of the new multi-step feedback scheme obviously excels that of single-step feedback. Additionally, under Neyman-Pearson criterion, the paper presents the fusion arithmetic corresponding to the new feedback scheme and the way of analyzing performance.
