Since ultra-wideband impulse waveform is directly related to communication system characteristics, so it is essential to select the suitable method to generate ultra-wideband impulse waveform. This paper uses Gaussian pulse and its derivatives to get the expected pulse signal, then it can get the power spectrum density by simulating Gaussian pulse and its derivatives, putting forward to get the optimized...
In the process of decision tree construction, property division standards directly affect the classification results. Aimed at weakness of ID3 in nicety of grading, we provide the concept of degree of rough classification as select criteria of separation of property. The method took into account nicety of grading and dependency between condition attributes and decision attributes. Compared with traditional...
Inspired from social swarm intelligence, a cooperative boundaries tracking model with a mobile sensor network based on social foraging swarm behavior. In the model, the nodes of mobile sensor network are viewed as simple intelligent individuals of social swarm. The cooperative moving of the individuals is driven by sensed distribution environment. For boundaries tracking problems with mobile sensor...
