In this work, the influence of characteristics efficiency of communication channel on the system’s performance of distributed detection algorithm based on using the soft decision scheme in the local sensors is analyzed. The dependencies of the total error probability of such algorithm on signal-to-noise ratio (SNR) channel with gaussian noise and fading is given. The gain in the detection efficiency by algorithm based on using the soft decision compared to the efficiency of hard algorithm is confirmed, even under fading communication channel. In addition, with such conditions, it was shown that system efficiency can be increased on account of increasing the number of sensors used.

摘要

In this work, the influence of characteristics efficiency of communication channel on the system’s performance of distributed detection algorithm based on using the soft decision scheme in the local sensors is analyzed. The dependencies of the total error probability of such algorithm on signal-to-noise ratio (SNR) channel with gaussian noise and fading is given. The gain in the detection efficiency by algorithm based on using the soft decision compared to the efficiency of hard algorithm is confirmed, even under fading communication channel. In addition, with such conditions, it was shown that system efficiency can be increased on account of increasing the number of sensors used.
