Antenna radiation pattern can be defined by photon probability distribution. Based on this, this paper points out that the negentropy of beamforming system relative to isotropic antenna system nearly equals to the system capacity improvement of wireless communication introduced by beamforming, which is constructed on the physical process of beamforming emission and the definition of traffic.
Quantitatively characterizing wind variation series in different environments is an important problem with significant engineering and industrial applications. We systematically carry out indoor and outdoor experiments separately to record two groups of wind speed time series. Using the Adaptive Optimal Kernel Time-Frequency Representation (AOK TFR) we first investigate the fluctuating behaviors from...
Noises exist in many measured systems inevitably. Therefore, noise resistance ability analysis is of great importance to accurately evaluate the performance of information analysis methods. In this paper, we systematically test the noise resistance ability of visibility graph (VG) and its generalization, i.e., limited penetrable visibility graph (LPVG). Taking the Lorenz system as the example, we...
Objective: To analyze the component law of Chinese medicines for gout, and develop new prescriptions for gout through unsupervised data mining methods. Methods: Chinese medicine recipes for gout were collected and recorded in the database, and then the correlation coefficient between herbs, core combinations of herbs and new prescriptions were analyzed by using modified mutual information, complex...
