Influence and its suppression of desired signal coupling to reference signal to interference cancellation system by Yun-hao JIANG, Zhi-hua ZHAO

“…The time-domain characteristics of adaptive interference cancellation system with desired signal coupling to reference signal were analyzed.The analyses reveal the desired signal makes the system a time-variation system and the optimal weights were changed,which made the performance of cancellation system decreased and infulence the reception of the desired signal.According to the coupling characteristics of common platform communication system,the formulas of (ICR) interference cancellation ratio and (DCR) desired cancellation ratio were gained in time-domain.The law of ICR and DCR varying with relative delay phase was got.The method of delay time matching was brought forward.Through matching the delay time of the extraction point of the reference signal to the output of the orthogonal divider and the receiv-ing antenna to the injection point of the synthetic signal could suppress the decrease of ICR for the reference signal coupling desired signal.The simulation results reveal that the delay time matching can not only prevent the decrease of ICR for de-sired signal in reference signal but also improve the performance of cancellation system.…”

PARAMETER ESTIMATION AND CONFIDENCE LIMIT CALCUALTION METHOD OF THREE-PARAMETER WEIBULL DISTRIBUTION by ZHANG JianFeng, XU Fang, ZHANG Yan, HUANG XiaoBo, JIA ZhuoHan

“…A correlation-regression method was proposed to solve the problem of low accuracy of parameter estimation and confidence limit calculation of the three-parameter Weibull distribution.The method was combined by the correlation coefficient method （Fu method） and the nonlinear regression method which makes full use of the convenience of Fu method and the excellent estimation effect of the nonlinear regression method in estimating the three-parameter Weibull distribution.In order to verify the effectiveness of the proposed method，the correlation-regression method，Fu method and Method combining maximum likelihood estimation and empirical formulae (referred to as the “MMPDS method”） were applied to the parameter estimation and confidence limit calculation of the data distribution of a certain alloy strength value with different sample sizes，and calculation consequence of different methods was compared and analyzed.Results show that the correlation-regression method has highest parameter estimation and confidence limit calculation accuracy among the above methods.When the sample size is less than 100，its advantage is more significant，and it can accurately calculate the parameters and confidence limits of the Weibull distribution.…”
