Equipped with large scale antenna arrays, massive multiple input multiple output systems are qualified with several benefits including enhanced throughput, power efficiency, and anti-interference ability, etc. The acquisition of such advantages requires adequate channel state information at transmitter. In frequency division duplex multiple input multiple output systems, channel state information...
A novel method is presented to recognize warheads in the ballistic missile defense. The normalized correlation coefficients and further the matching scores between range profiles (RPs) of warhead are first calculated. By introducing a threshold, the warhead and decoy can be separately classified. The distribution of these results is then modeled as a mathematical model. Based on such distribution,...
Accurate modeling of the ship-to-ship (S2S) fading channels is critical not only to the shipborne automatic identification system design but also to the verification and performance evaluation of other maritime wireless communication systems. The statistical properties of S2S fading channels are quit different from either the terrestrial-based mobile communication channels or the typical fixed-to-mobile...
