Computer technology and its relative subjects developed at very high speed in recent years, so is geo-information science, including Geographic Information System (GIS), remote sensing (RS) and global position system (GPS). But with the increase of data, many data cannot be used efficiently because of the tremendous amount of data and information and the(More)
An elliptical basis function (EBF) network is proposed in this study for the classification of remotely sensed images. Though similar in structure, the EBF network differs from the well-known radial basis function (RBF) network by incorporating full covariance matrices and uses the expectation-maximization (EM) algorithm to estimate the basis functions.(More)
The multiuser transmission (MUT) is an effective way to eliminate the multiple-access interference (MAI) and the inter symbol interference (ISI) in the downlink channel of TDD-CDMA. In this paper, a novel MUT model is developed. In the model, the MUT combined with smart antennas (SA) is taken to improve the performance of TDD-CDMA in the spatial-temporal(More)
