The distributed detection arithmetic with fading channel based on the minimum error probability

In the actual detection, due to bandwidth, channel fading and channel noise, the ideal channel isn't assured from the local detector to fusion center, so the optimal detection arithmetic is rectified accordingly. In this paper, we study the global optimal detection algorithm based on the two kinds of non-ideal channel schemes, the first, channel state information is known; the second, channel statistics characteristics is known. The configuration of the system is mixture of parallel and serial structure. The decision rules of the every local detectors and every local processor must be optimized jointly based on the minimum error probability. Stimulation result shows that the performance of the second channel schemes suffer small performance loss compared with the first channel schemes, but its calculation is simplified and it is applied much more practically.
