Blind estimation of spreading sequence of CDMA signals based on Fast-ICA and performance analysis
Published 2011-01-01“…The DS-CDMA signals can be divided into two types,the short-code(SC) and the long-code(LC) DS-CDMA signal.The existing methods are only used to estimate spreading sequences of SC-DS-CDMA signals,which cannot work for the LC-DS-CDMA signals.A new blind estimation algorithm for DS-CDMA signals based on fast independent com-ponent analysis was proposed by analyzing the mathematical model of the LC-DS-CDMA signal and the estimation per-formance of the proposed algorithm in theory was deduced.Moreover,the proposed method not only applies to the LC-DS-CDMA but also SC-DS-CDMA signals.The theoretical analysis and simulation results verify the effectiveness of the proposed algorithm.…”

Template attack of Crypto chip based on clustering
Published 2018-08-01“…The known-key establishment template and others full control of experimental equipment preconditions are required to implement the traditional template attack.The preconditions restrict the application scenario of template attack.The template attack is only applied to the device that the key input can be controlled.In order to resolve the restrictive preconditions,a novel method of template attack based on clustering was proposed.The clustering EM algorithm was modified according to the characteristics of information leakage model in the method.The modified clustering methods accurately fitted the leaked information probability model in the case of unknown key,the location of information leakage could be determined.Then the attack established the templates in the location,and implemented template matching.The proposed method eliminates the dependence of traditional template attacks on per-conditions and expand the application scenario of template attack.…”

Particle filtering based semi-blind estimation for MIMO-OFDM time-varying channel
Published 2007-01-01“…A semi-blind channel estimation method based on the particle filtering was proposed for the MIMO-OFDM wireless communication system.By optimizing the particles distribution locally,the traditional particle filtering algorithm was modified,and a local optimized particle filtering was proposed.This local optimized particle filtering can achieve the low MSE,and improve the precision of the MIMO-OFDM time-varying channel estimation.Since this method was per-formed in frequency domain,it was not necessary to know(or estimate) the length of the channel.Compared with exist-ing approaches,the proposed method was more robust to the non-gauss distribution noise and the detection performance is nearly optimal.The simulation results show the effectiveness of the proposed method.…”

Performance analysis of incremental cooperative relaying system over composite multipath/shadowing fading channels
Published 2014-12-01“…Since the performance metrics of digital communication systems over composite multipath/lognormal fading channels is intractable,a mixture Gamma (MG) fading model is used to approximate Nakagami-lognormal (NL) fading model.By using MG fading channel model,some exact closed-form expressions of the average error rate and outage probability for incremental cooperative relaying system are obtained,respectively,where per hop is independent and non-identically distributed.Finally,numerical and simulation results are shown to verify the accuracy of the analytical results.These results show that it is helpful to approximate the composite NL distribution by using the MG distribution in the performance analysis of cooperative relaying systems.…”
