In this paper, an efficient three-dimensional (3-D) alternating direction implicit finite-difference time-domain (ADI-FDTD) algorithm has been used to analyze the electromagnetic characteristics of ultra-wideband wireless channel. Conventional FDTD has been successfully used for the electromagnetic analysis of wireless channel. However, there is one of the major limitations of FDTD, which is that...
Ground penetrating radar (GPR) is a non-destructive and non-intrusive subsurface investigation equipment which has been widely used in the field of civil engineering. As the GPR signals are easily corrupted by noise, so it's always difficult to detect the multi-layer reflection signal of the pavement. To address the problem,In this paper we present the wavelet transform modulus maximum de-noising...
Ground penetrating radar (GPR) is a non-destructive and non-intrusive subsurface investigation equipment which has been widely used in the field of civil engineering. Some challenges which GPR encountered for pavement subsurface inspection are: 1)GPR signal are easily corrupted by noise; 2) commercial GPR whose resolution is depended on system bandwidth, is not suitable for ultra-thin thickness estimation...
