- 摘要：The design of secure wireless communication suffers a great challenge for openness of wireless channel and the broadcast nature of radio signals.The security problem introduced by wireless channel may be solved adequately by wireless channel itself.The space redundancy is often used in existing physical-layer security method to enhance security.So the concept of γ mean square error is proposed in the paper,which is used to introduce redundancy for pre-coding weight.The concrete analysis and corresponding formal derivations are also given in the paper.Based on these,a novel physical-layer encryption method is proposed according to short-term reciprocity,rapid Decorrelation of wireless channel.Simulation results show that the proposed method guarantees wireless transmission in the authorized receiver and reduces the probability of interception.关键词：physical-layer security;wireless channel;low probability of interception;Γmean square error2|1563|2更新时间：2025-07-08
- 摘要：For nonlinear estimation with additive noise,we utilized the sparse-grid theory to propose a novel nonlinear filter,Sparse-grid Square-Root Quadrature Filter (SSRQF).The quadrature points for the conventional QF increases exponentially with the dimension.However,the new filter SSRQF uses the sparse-grid theory to reduce the number of quadrature points to a polynomial with the dimension,which alleviates the computation burden greatly.Through the theoretical analysis,we proposed that Unscented Kalman Filter (UKF) is only a special case for Sparse-grid Quadrature Filter (SQF),thus SSRQF is more flexible in terms of choosing points and controlling accuracy.The simulation results show that the SSRQF achieves higher accuracy than the UKF and the Extended Kalman Filter (EKF).Thus,it is a high accuracy nonlinear filter algorithm with computationally efficient.关键词：nonlinear filter;sparse grid;Gauss-Hermite quadrature;quadrature filter;unscented Kalman filter2|2258|4更新时间：2025-07-08

- 摘要：A Transform Domain Anti-Interference Method based on fast algorithm Cosine Modulated Filter Banks (CMFB) and Sine Modulated Filter Banks (SMFB) combining spectrum estimation is proposed.Compared with existing CMFB Transform Domain Anti-Interference Method,this method not only avoids the signal phase effect on the amplitude spectrum,but also enhances the excision capacity of short periodic stationary signals.For increasing the technical realization,fast algorithm structures of CMFB and SMFB are obtained by improving and supplementing the CMFB fast algorithm by Malvar,and then used to the proposed Anti-Interference method.The simulation and recourse analysis confirm that the multiplication and the addition of the proposed Method are just 75% and 45% of the overlapped-and-add DFT Anti-Interference Method,when the bit error rate performances are close to each other and sub-filters are enough.关键词：transform domain anti-interference;cosine modulated filter banks (CMFB);fast algorithm2|1467|0更新时间：2025-07-08

- 摘要：This paper considers linear transceiver design for amplify-and-forward multiple-input multiple-output (MIMO) multiple-relay systems,aiming to minimize the mean squared error (MSE) under the total relay transmit power constraint.We first introduce the singular value decomposition (SVD) of matrix product and simplify the original optimization problem to one which takes a singular value vector and a unitary matrix as optimization variables.By employing variable substitution and penalty term,the simplified problem only has one unitary matrix constraint.Then we develop a new Riemann Euclidean steepest descent algorithm to deal with the unitary matrix constraint.Finally,simulation results demonstrate that the performance of the proposed scheme is better than traditional schemes and closes to the lower bound of MSE.关键词：multiple-input multiple-output (MIMO);multiple-relay;mean squared error (MSE);linear transceiver2|1998|1更新时间：2025-07-08
- 摘要：The LFM signal and noise could be separated more effectively by FRFT than by traditional FFT.The energy gathering of FRFT spectrum is effected by duty ratio and FM bandwidth.With small duty ratio and wide FM bandwidth,the spectrum peak of FRFT would not be very sharp.The article presents a new slipping window way used in fractional Fourier filtering of LFM signal.The effect of time and frequency intercept in FRFT is also analyzed.A differentiation principle used in LFM signal detection under the condition of low SNR is provided based on the analysis before.Also,the filtering process in fractional Fourier domain is discussed in detail.It is indicated by the emulation result that blind signal could be processed by the filtering way in pipelining mode with little noise energy.The SNR could increase more than 10dB.It also indicates that the effect is improved in radar deception jamming domain.关键词：fractional Fourier transform (FRFT);time and frequency intercept;fractional filtering;deception jamming2|1503|9更新时间：2025-07-08
- 摘要：A method of DCF (Distributed Coordination Function) optimization—Stop and Wait DCF integrated with the rate control and its performance analysis model are proposed in order to increase the effective throughput.SNR (Signal to Noise Ratio) thresholds of rate control are determined by tuning the BER (Bit Error Rate) of frame with the help of AMC (Adaptive Modulation and Coding) technology.When the SNR is below the lowest threshold,the DCF backoff process stops and waits till the channel SNR becomes big enough again.Therefore the transmission error could be decreased.Meanwhile,the access collision could be reduced either.Since the channel time,collision probability and frame error rate are changed differently as tuning BER,maximized throughput can be get at the tradeoff point of these parameters.The analysis and simulation indicate that the proposed model is accurate.The problem without packet loss differentiation is overcome and the cross layer optimization is implemented.关键词：IEEE 802.11;distributed coordination function(DCF);rate control;adaptive modulation and coding;optimization2|1594|0更新时间：2025-07-08

- 摘要：In a shared-cache multi-core architecture one thread may interfere with a second thread if the second one tries to access the shared cache simultaneously.Consequently,this causes the eviction of the second thread instructions.To track this challenge,designers need to consider runtime inter-thread interference while analyzing WCET of a real-time application on multi-core architectures.This paper proposes an iterative approach for WCET estimation which considers the circular dependence between shared bus and the runtime inter-thread interference in shared cache.Our approach analyzes inter-thread interference in shared cache based on access timings,which combines static analysis and dynamic timing estimation.The iterative method presented can improve the tightness of WCET estimation by refining estimations of inter-thread interference.Our experiments demonstrate that the proposed approach can reasonably estimate inter-thread interference in shared caches and improve the tightness of WCET estimation by an average of 21% and 14%,compared with the estimations in literatures.关键词：multi-core architecture;shared cache;shared bus;interference;WCET2|1572|4更新时间：2025-07-08
