Coherent Distributed Detection Using Inhomogeneous Sensors Under Local Power Constraint
In this paper,we consider the problem of local power constrained coherent distributed detection over fading multi-access channel (MAC).The deflection coefficient maximization (DCM) is used to optimize the performance of fusion system under local power constraint of sensors.We use the statistical information of channel gain to obtain the deflection coefficient of the detection statistics at the fusion center.We derive the closed-form solution to the considered optimization problem.Monte-Carlo simulations are carried out to verify the performance of the proposed method.Simulation results show that the proposed method could significantly improve the detection performance of the fusion system under local power constraint and low signal-to-noise ratio (SNR).
