Efficient Transmission Scheme for Distributed Signal Detection with Noisy Communication Links
Xiang‐Yang Liu, Yu Liang Cong, Jian Yang · 2018
We consider the problem of distributed signal detection in a wireless radar sensor network with sensors having non-ideal communication links to the fusion center. Other than the research of the optimum detection scheme, we focus on the efficient transmission of given sensor decisions at the cost of slightly lowering the detection probability at the fusion center. To do so, we introduced two quantities, i.e., detection probability loss coefficientand communication gain coefficient. By studying their curve, an efficient transmission scheme can be found with detection probability loss less than a prescribed small value. A procedure was given, and the simulation results illustrated the effectiveness of the proposed method.
