Modified Analog Transmission Scheme for Distributed Detection

In this paper, we consider the design of a modified analog transmission scheme for binary distributed detection systems in which the compressed information made by the local sensors are sent to the fusion center (FC) over parallel Rayleigh fading channels. For complexity concerns, we focus on the equal gain combiner fusion rules. Simulation results show that, without increasing extra transmission costs, the proposed transmission scheme can achieve significant performance gain not only over that of the widely adopted binary transmission scheme but also over that of the simple analog transmission scheme.
