The purpose of this paper is to present some issues that arise when applying a traditional continuous-time approach to system identification. In particular, we consider the bias that is introduced into the continuous-time model through the use of sampled data which is filtered to recover the derivative of the continuous time signals. We find that this error has two constituent components, one being...
In code-division multiple-access (CDMA) system, ill-conditioning of the covariance matrix of the received signal may degrade the performance of minimum mean-squared error (MMSE) detector, especially when signal-to-noise ratio (SNR) is high and small data sets are available for covariance matrix estimation. In order to mitigate the performance degradation, we propose a blind multiuser detection method...
Using the Haar wavelets to expand the input signal and the output signal, then using the generalized Haar wavelet operational matrix of integration, we present a method to solve numerically the fractional Riccati differential equations. The results of the comparison with other methods indicate that the proposed method is simple and feasible.
This paper is a description of our efforts to create a queueing model for parallel connection servers with different dispatch probabilities, so that we can estimate the system response time of parallel Web servers. First, we calculate the system response time of the parallel connection servers with different dispatch probabilities. Second, we simulate the queueing model of the parallel connection...
National Development and Reform Commission of China has agreed to build 10 GW wind power base along Jiangsu coastland, which has plentiful wind power resources, and Jiangsu Province will be one of the seven wind power bases in China. Wind power's random variability is the main impact on power system, where there is higher portion of wind power, there is more impact. In this paper, from power system...
Color space conversion is the core issue in color management. Printers and image setter express color with CMYK space. But if color is edited and corrected in the CMYK space, it will cause a greater loss of color, and the Computing of computer will also be slowed down. So it often needs to be converted to a LAB uniform color space. Among the previous conversion methods, there is a widespread problem...
