In this paper we jointly consider statistical precoding and statistical bit allocation for transmission over correlated MIMO (multiple-input and multiple-output) channels with a linear and zero forcing receiver. Assuming the statistics of the channel is available to the transmitter, we will derive BER bounds using the statistics of subchannel error variances. The bounds are then used to design statistical...
Teaching efficacy is an important aspect of military institute of professional education. Paying attention to enhancing teaching efficacy is an important task to development and study professional education of military. The paper discussed the meaning of the sense of professional education teaching efficacy, analyzed its functions and characteristics from different aspects, proposed strategies to...
Researching on the relationship between perceptual characteristics of driver and traffic safety in expressway tunnel group, a test of 160 drivers is made with the speed anticipation reaction tester and depth vision tester in the Tongling to Tangkou (Anhui) traffic tunnel group. The data are t test and variance analysis. According to the thought of gray system, gray relation analysis model of the perceptual...
3D reconstruction based on high-level features, such as line and plane, is a significant development trend in Digital Photogrammetry and Computer Vision. Moreover how to rapidly realize 3D visualization of street landscape is very important for cyber city's 3D modeling. In order to improve efficiency of street 3D visualization and reduce human-computer interaction, a scheme with high feasible and...
Image mosaic technique is used to create vast scene images and panoramic images. It has widespread use value in the cultural heritage protection and virtual reality field. As we know, there are many methods of image mosaic, such as feature points and binary image region matching, etc. However, the traditional processing methods always ignore speed or precision or practical scale; that is to say, they...
