The narrow bandwidth of microstrip antenna is one of the important features that restrict its wide usage. An enhanced bandwidth design technique is presented in this paper. By loading different shapes of slots on parastic patch, the broad-band microstrip antennas is obtained. Utilizing this design technique, broad-band microstrip antennas have been proposed. To confirm the applicability of the method for the designs of antennas at C-band, simulations and experiments have been carried out. The measured results show that the proposed antennas have a relative bandwidth of up to 13%, and have a broad-band antenna gain no less than 6dB.

The problem of tracking the direction of arrivals (DOA) and the direction of departure (DOD) of multiple moving targets is considered in bistatic multiple input multiple output (MIMO) radar. A low complexity angle tracking algorithm in bistatic MIMO radar is proposed. The proposed algorithm derived the difference between previous and current covariance matrices. And the relationship between the different of covariance matrices and the different of target angle is derived. The performance of the proposed algorithm is improved by averaging the covariance matrix elements. Last DOD and DOA are got by least square method. This algorithm avoids the decomposition of the covariance matrix and reduces the computational complexity, which realizes DOA and DOD of the adjacent moment automatic association. The simulation results demonstrate effectiveness of the proposed algorithm. The algorithm provides the technical support for the practical application of MIMO radar.

A three-dimensional registration method based on natural feature points is presented, which is applied to the augmented reality system. Firstly, several common feature extraction algorithms have been compared in this paper, and the SIFT algorithm is applied to improve the matching accuracy as a descriptor matching method. And then the data of ten key image frames is used to reconstruct the 3D structure of the scene. When the real-time image data is input, the key frame which mostly matches the current image is selected, and the image matching method based on key frame is used to obtain the camera pose. Finally, improved Lucas-Kanade method for real-time tracking is adopted, not only maintaining the accuracy of registration but reducing the system computing time. The experimental results shown that the method achieves a effect of real-time tracking and accurate registration, and can keep a better registration precision.

A three-stage transformer-coupled 160 GHz CMOS low noise amplifier (LNA) with noise-reduced and gain-boosted techniques is presented in this paper. The noise-reduced technique is realized by employing an inductor between common gate and common source in one cascode stage, while gain-boosted technique is achieved by using an inductor in the gate of common gate stage. Both techniques aim to obtain high gain and low noise concurrently. The proposed LNA is fabricated by GF 65 nm CMOS process. From post-simulation results, this LNA realizes a 13.8 dB gain and a 7 dB noise figure at 160 GHz, and draws 28.4 mA current from a 2 V supply.

Based on the small perturbation method (SPM), a basic model is established to study the electromagnetic scattering of Gaussian rough surface. By using the small perturbation method, the relationship between scattering coefficient and scattering angle is given when scattering azimuth, incident angle, relative permittivity and relative permeability are changed respectively. Then we find the common points between them so that we can establish the relation model between scattering angle and scattering coefficient. In order to validate the accuracy, the specific parameter values are brought into the established model. The results show that the numerical results are basically the same as the modeling results, and the error is very small. Therefore, when the statistical parameters of the rough surface are determined, a model between scattering coefficients and scattering angles can be established to simplify the calculation of scattering coefficients.

Current progress in network techniques and the complexity of network structures require network administrators to spend more time and attention on maintaining a network system under normal operations. With our continuously increasing dependence on networks, it is difficult to know how to effectively manage all of the equipment in a network and to be certain of whether the network is operating correctly. To make a comprehensive survey of current administrators' management modes, administrators must understand the rules for the network's equipment and the entire topological structure of the network; such an understanding will allow them to rapidly and efficiently address an increasingly complicated network environment. This paper presents a hierarchical divisive algorithm for topology discovery that can work on a network layer and a link layer, which are widely used by network administrators today. This approach involves an automatic exploration through a random network node and possesses the features of cross-layer and multiple protocols to support the exploration of a multi-subnet network, to enable a faster and more effective explorative ability of a topological resource. The implementation shows how to automatically discover the entire network's topology and all of the network's equipment link nodes from the integration of a network-managed system to prove that our proposal is effective.

With the growth of wireless communication services, large base stations will not only produce a lot of electromagnetic radiation, but also bring huge energy consumption, resulting in a large number of greenhouse gases. The fifth generation mobile communication will deploy the macro base stations and the micro base stations in multi-layer heterogeneous network to enhance the system network performance, reducing the negative impact of above-mentioned factors. According to the theory of cell communication, in this paper, by adding the micro base stations distributed in different grid modes in the surrounding area of the macro base station, the purpose is to maximize the total area covered by the base stations in the cell under the condition that the total power consumption of the base stations is not increased.

The current analysis restricts to the statistics of different exceedance events in flight operational quality assurance (FOQA). Statistical methods lack effective correlation to flight data at different time and space, and lack deep-level mining and application of flight quality monitoring information. For questions raised above, this paper presents a novel approach for FOQA based on temporal geography information system (T-GIS). We construct a time-snapshot-> time series-> space-time evolution model, and design a dynamic spatiotemporal statistical analysis algorithm. The results show that the system can be used to deal with large flight data to find the unsafety events spatial-temporal distribution of the whole civil aviation industry. It also provides a new research idea to raise the level of FOQA.

With the rapid development of world economic integration, the importance of container in modern logistics system is becoming more and more prominent. However, the status of products in containers is opaque in highway freight. So this paper designs a real-time monitoring system for status of products in logistical containers based on cloud computing and compressed sensing. This monitoring system consists of the perception layer, the network layer, the cloud service layer and the application layer. In this system, temperature, humidity, vibration intensity, ethylene concentration and oxygen concentration of the container which are measured in perception layer are transmitted to the sink node. Compressed Sensing (CS) is designed in the sink node in order to compress the acceleration data, since the amount of the data is too large. These measurements of the acceleration data together with other sensor data are sent to cloud service layer through the network layer. The cloud servers integrate, store the data, and decide the current logistical environment whether meet the transportation requirement of products. The application layer fetches the data from network layer, displays them by graphics and tables, and alerts the drivers if necessary.

Spatial Modulation (SM) is a variant of the Multiple-Input Multiple-Output (MIMO) technique with only one antenna transmits signal at a time. It has the advantage of inter-antenna interference avoidance. Therefore, most of the antennas are idle during the signal transmission. Many literatures have been proposed to use multiple antennas to improve the bit error rate (BER) and bandwidth efficiency for the SM. In this paper, we propose a maximum combination spatial modulation (MCSP) to improve the Bit Error Rate (BER) performance of the related SM methods. Results show that the proposed method can improve the BER and can also increase the throughput for the conventional SM method.
