This paper studies a resource allocation scheme and precoding design to increase the number of quality of service (QoS)-satisfied user equipments (UEs) for multicell multiuser multiple-input-multiple-output downlink systems. The main challenge in such multicell systems is the co-channel interference, including intra-user interference (IUI) and inter-cell interference (ICI). To deal with both IUI and...
This paper examines a new measure of empirical research based on principal component analysis. We can interpret the results by employing the technique as: 2001–2010 scientific and technological competitiveness in Shanghai showing the trend of continued growth, especially in recent years maintained an accelerated increase; the main affecting factors are scientific and technological inputs and outputs...
Principal component analysis (PCA) combining with multivariate statistical knowledge is used for the sensor fault detection and diagnosis according to the characteristics of the satellite attitude control system. In this paper, the principle of PCA to detect faults is presented, and the conventional PCA fault isolation approach is improved. The example of using PCA to fault detection and diagnosis...
