摘要:This Letter presents a dual-band filtering power divider (FPD) by employing square-loop resonator loaded by open stubs. The even- and odd-mode equivalent circuits of the proposed resonator are analysed and design equations are derived. For demonstration, the power divider (P...

摘要:A novel region-scalable fitting (RSF) active contour model with symmetric cross entropy (SCE)-based global constraint is proposed to segment various kinds of images. The energy functional is mainly composed of two parts, namely the local and global constraints. The local constrai...

摘要:Intrusion detection is a prevailing area of research for several years, and numerous intrusion detection systems have been proposed for industrial control systems (ICS). In recent ages, the attacks like seismic net , duqu and flame against ICS infrastructures have instigated grea...

摘要:Increasingly popular online social networks contribute to the massive growth in mobile traffic. The authors find that social network data, which is easier to obtain than carrier data, can be used to optimise the deployment of small base station (SBS). In this Letter, the authors ...

摘要:Most adaptive filtering schemes employ the tapped-delay line. In part, such a fact can be explained by the assumption that the plant they intend to estimate is linear. Although such a hypothesis can be reasonable if the input signal is constrained to a certain range, sometimes it...

摘要:Several approximate matrix inversion methods have been used in linear massive MIMO uplink detectors where their convergence rate, performance, and complexity are greatly affected by the initial solution. In this Letter, the authors exploit a stair matrix, instead of a diagon...

摘要:A compact Ku-band bandpass filter is proposed by using low-temperature cofired ceramic (LTCC) technology in this Letter. For miniaturisation, the folded dual-composite right- and left-handed (D-CRLH) resonator is introduced. By folding the inter-digital capacitor and microst...

摘要:This Letter investigates the impacts of hardware impairments (HIs) and channel estimation errors (CEEs) on the performance of non-orthogonal multiple access (NOMA)-based satellite communication networks. Especially, the authors obtain the closed-form expression of the outage prob...

摘要:A background bit-weight calibration in pipelined successive approximation register ADC is proposed. By exploiting the conversion results of the first stage to determine the injection of the dithered signal and introducing two extra capacitors into the first stage to reduce the ra...

摘要:This Letter proposed a polarisation detection sensor by utilising electro-optic (EO) crystals in purpose of tumour's boundary detection. In this work, efficiency of uniaxial (anisotropic) EO crystals like CdTe and isotropic EO crystals such as polymer-dispersed liquid crystal (PD...
