The OFDM system based on the fractional Fourier transform (FRFT-OFDM) is robust against fast-fading channel. However, the performance of anti-jamming is not analyzed. In this paper, the anti-jamming performance of the FRFT-OFDM system under multitone jamming (MTJ) and linear frequency modulated (LFM) jamming is evaluated. The evaluation is carried out by calculating bit error rate with probability...
When the conventional method of parameter estimation is used to construct the RPC model, the uncertain factors can result in inconsistency between the RPC model and the reality. The inconsistency shows up as evident systematic error in the constructed RPC model. To tackle the problem, a non-parametric component is introduced on the base of the parametric model to account for the unknown factors and...
Customer is one of the most important resources of an enterprise. Customer value analysis is the basis of customer relationship management and customer classification is an important item of customer value analysis. Aiming at the characteristics of customer in the mobile telecommunication industry, the thesis designed the BP neural network model, and presented the doable evaluating programs using...
