MAC protocol for measurement signal broadcasting in distributed ocean current estimation using underwater acoustic sensor networks

Hao Chen Huifang Chen Min Deng Lei Xie

This paper presents a media access control (MAC) protocol for distributed ocean current estimation using the underwater acoustic sensor network (UWASN). We present a spatial reuse time-division multiple access (TDMA) protocol. Based on measurement signal broadcasting process, we formulate the slot scheduling problem with a specific objective as an optimization problem that we resolve with a heuristic algorithm. We use computer simulations to analyze the proposed TDMA protocol's performance.

A New Method for Direct Signal and Multipath Clutter Cancellation in Passive Radar

Hongchao Lu Li Sichuan Min Deng Jin Tan

It is a problem in passive radar that direct signal and multipath clutter is much stronger than the object echoes. Existing cancellation methods always impose that the arrival time of clutter is integer multiples of sampling period, which is impossible for real radar system. To solve the problem, a novel method of clutter cancellation using arrival time exactly estimation is proposed. Simulation results show the effectiveness of the new method.

A Multi-restrained Terminal-controlled Access Network Selection Strategy

Advances in engineering research/Advances in Engineering Research (2015)

Yi Jiang Min Deng Hao Feng

Keyword: heterogeneous wireless networks; access network selection; multiple restrictions; cost function; parallel transmission Abstract. Next generation network must be a situation that a variety of RATs (radio access tech- nologies) coexist and integrate. Aiming at improving user's QoS (Quality of Service) effectively, a mobile terminal access network selection strategy with multi-constraint conditions is proposed. Based on the preferences of user and QoS standards of multiple access networks, the strategy con- sidered different types of business and their priorities at the same time, and given the cost function for each wireless network. According to the minimum and best principle, the Strategy selected the most suitable network combinations to do parallel transmission. Simulation results show that the strategy can greatly improve the data transfer rate, as well as decrease the traffic blocking rate.

A Surface Reconstruction Algorithm Based on 3D Point Cloud Stratified Sliced

XIAO Weifeng -Min Deng Chaokui Li

This paper presents a novel surface reconstruction algorithm based on 3D point cloud sliced by a series of planes vertical to Z-axis. First, the density and distribution of point cloud is analyzed in vertical direction Z-axis and a stratified point cloud model is put forward to present an object feature, in which point cloud is sliced with irregular intervals. An approach of stratified point cloud projected on plane is proposed. The algorithm based on Delaunay triangulation technique in two dimensions gain quickly the local topological connection relationships between points. Further, the planar triangular mesh is mapped into 3D-TIN. Finally, the object surface model is composed of the stratified 3D-TINs with consistent edges. Two tests are implemented to demonstrate that the algorithm is very simple, robust and suitable to reconstruct the object surface based on complex shaped and irregular 3D point cloud.

Near-infrared dual-band sensing of trace volatile organic compound gases via metal-organic framework patch array integrated on metal film

Optical Engineering (2024)

Min Deng Yongqiang Zhou Jiaojiao Wang Yunqing Lu Jin Wang

We propose a hybrid plasmonic zeolitic imidazolate framework-8 (ZIF-8) nanostructure to achieve near-infrared dual-band sensing of trace amounts of volatile organic compound (VOC) gases via metal-organic framework patch array integrated on metal (Au) film. To achieve dual-band VOC gas sensing, two absorption peaks related to the surface lattice resonance (SLR) and surface plasmon polaritons (SPP) resonance are constructed in this plasmonic structure, to match the near-infrared absorption bands of methane and ethanol gas molecules respectively. For an 80 nm thick Au layer, the height and width of ZIF-8 patch and the gap between ZIF-8 patches are optimized to be 0.86, 0.925, and 0.43 μm. Then, this structure shows an SLR at 1392.64 and a SPP resonance at 1653.72 nm, which have peak intensities of 0.735 and 0.855, and the Q-values of 1435 and 253, respectively. Furthermore, the third resonance peak related to the Fano resonance is investigated and can be considered as a feasible alternative to calibrate the measurement without external references.

BIAS analysis of an algebraic solution for TDOA localization with sensor location errors

Anran Yang Fucheng Guo Le Yang Min Deng E. Jiang

The nonlinearity inherent in the time difference of arrival (TDOA)-based source localization problem leads to biased source location estimates. The estimation bias of the closed-form TDOA-positioning technique, two-stage least squares(TSWLS) technology was established analytically in previous works. This paper extends the theoretical developments in the case where there exists no sensors location errors to investigate the bias of TDOA-positioning in the presence of sensor location errors. Specifically, the estimation bias of the algebraic two-stage TDOA localization algorithm proposed is derived. Simulations validate the obtained theoretical results. It is shown that different from the findings in previous works where the estimation bias of the two-stage solution mainly comes from its Stage-1 processing, both stages of the localization algorithm considered in this work can introduce significant estimation biases when sensor location errors are present.

Wave Height and Wave Period Measurements Using Small-Aperture HF Radar

IEEE Transactions on Geoscience and Remote Sensing (2022)

Min Deng Chen Zhao Zezong Chen Fan Ding Ting Wang

A small-aperture receiving array occupying a small area provides convenience for the layout of HF radars. However, this kind of antennas has a wide beam, which adversely affects wave measurements. To solve this problem, a method for extracting wave parameters from wide-beam radar echoes, that models current variations across the beam, is proposed in this article. The nondirectional wave spectrum is extracted from the echoes of a small-aperture HF radar and wave parameters such as the significant wave height, the peak and mean wave period are then calculated from it. Simulation is carried out to assess the performance of the method for different current velocities, radar frequencies and wind conditions. The proposed method is then applied to a 9-day data set collected by an MHF-C radar for further validation via comparisons between the radar-estimated and the buoy-measured wave parameters. Some factors that may affect the performance of wave height measurements are analyzed, such as the signal-to-noise ratio and radial current velocity. The correlation coefficient (CC) between the radar-estimated and the buoy-measured significant wave height is 0.90, and the root mean square difference (RMSD) is 0.51 m. For the mean wave period, the CC is 0.61 and the RMSD is 0.67 s. The results demonstrate that the significant wave height and the mean wave period extracted by the proposed method are consistent with the buoy-measured values and the proposed method can overcome the broadening influence of the Doppler spectrum caused by ocean currents.
