This paper deals with the problem of blind estimation of the spreading sequences in multi-rate direct-sequence code division multiple access(DS-CDMA). The characteristic of the down-link Multi-Rate DS/CDMA signal is analyzed, and the down-link Multi-Rate DS/CDMA signal is modeled as the blind source separation pattern at first. Then an efficient iterative dimension-increased method based Fast-ICA...
As an effective tool to raise the business management level comprehensively, ERP(Enterprise Resources Planning) is becoming the modern enterprise's movement pattern; however its complex internal function structure as well as the flexible application pattern, actually intensify the technical difficulty of Audit and cause the audit environment to be more complex. How to resolve the problem under the...
This paper analyzes the dialectical relationship between coal consumption and environment and economic growth; meanwhile discusses the reasonable coal consumption patterns based on constraints of economic growth and environment, which is of significance to ensure the sustainable development of the coal industry.
As an important component of self-control mechanism, the internal auditing plays an important role in commercial banks. There are many weaknesses in internal auditing of China's commercial banks, thereby affecting the internal auditing to function effectively. In this paper, from the corporate governance perspective, based on the analysis of on the problems existed in China's commercial banks, the...
As a developing country, China has confronted with dilemma of coal consumption and environment: Coal is indeed China's double edged sword-the new economy's black gold and the fragile environment's dark cloud. The article makes an overview of China's coal consumption and environmental challenges, and describes the ASC and IGCC technology designed to reduce pollutants, including the greenhouse gas carbon...
In order to analyze the spatial structure of the leaf area index (LAI) of the spring soybean which was planted in late April and was harvested in early October, it was the LAI of the soybean as the breed of Jinda 74 that was studied in this paper in detail on further guiding the fine cultivation for this kind of the soybean, which was grown in the most of the China. During this research, the 54 sampling...
In this study, La 62.0 Al 15.7 (Cu 0.5 Ni 0.5 ) 22.3 bulk metallic glasses (BMGs) were prepared by copper mold casting method, and the effects of the pressure treatment up to 5.0 GPa at room temperature on structural relaxation were investigated by X-ray diffraction (XRD) and differential scanning calorimeter (DSC). The results showed that structural relaxation...
Based on first-order and second-order phase difference, an algorithm for the modulation recognition is developed in this paper. A method based on instantaneous autocorrelation which can obtain the first-order phase difference is given in this paper, which needn't reveal the phase ambiguity. In order to improve the performance of recognition, N-overlapping phase difference is developed. Several simulations...
