Abstract EN
The problem of optimal power constrained distributed detection over a noisy multiaccess channel (MAC) is addressed.
Under local power constraints, we define the transformation function for sensor to realize the mapping from local decision to transmitted waveform.
The deflection coefficient maximization (DCM) is used to optimize the performance of power constrained fusion system.
Using optimality conditions, we derive the closed-form solution to the considered problem.
Monte Carlo simulations are carried out to evaluate the performance of the proposed new method.
Simulation results show that the proposed method could significantly improve the detection performance of the fusion system with low signal-to-noise ratio (SNR).
We also show that the proposed new method has a robust detection performance for broad SNR region.
