Adaptive behaviours of nodes can cause the evolution of networks. To investigate the characteristics of evolutionary complex networks that result from the interactions between agents in complex adaptive systems, we construct a complex network model of heat-bug interactions by drawing on statistical physics methods based on the heat-bug experiment. The networks of interactions between heat bugs show...
Traditional definitions of dissipativity require an assumption that the admissible control should guarantee that the system has a unique solution and the supply rate is locally integrable. In this paper, by introducing the first exit time from a changeable domain of state and input, a novel dissipativity in the local form and the global sense is defined based on some easily-checked conditions. By...
Sparse decomposition-orthogonal matching pursuit is applied to array signal processing field, and a new method for multi parameters estimation of wideband Chirp signals based on orthogonal matching pursuit decomposition is presented. At first, according to wideband Chirp signal geometry, we establish the over-complete dictionary and do OMP decomposition to the array receive signal on the over-complete...
In this paper, the signal model and expression in time domain of DS-UWB signal are introduced, and an approach using eigen-analysis of correlation matrix for DS-UWB signal is proposed to blindly estimate the PN sequence and several parameters in low SNR DS-UWB signal. Compared with the previous methods, both synchronization and PN sequence estimation can be realized simultaneously by the approach...
