Object track is a hot topic in the field of Cyber-Physical Systems (CPS). Because the existing object tracking algorithm, which is based on Scale-invariant feature Transform (SIFT) and Particle Filter (PF), will make the feature points of target model be all deleted and not be added during the period of the full occlusion of the target, it isn’t able to work. According to this problem, this paper introduced adaptive updating target model and object matching. The specific method is taking a object tracking method of SIFT and PF, taking Random sample consensus (RANSAC) to exclude error matching, stopping updating object model while establishing candidate one due to the losing of tracking object, and matching objects by Best Bin First (BBF) optimized by k-dimensional tree (k-d tree). The simulation results show that this method was robustness when the object reappeared after full occlusion.
物体轨迹是信息物理系统(CPS)领域的研究热点。现有的基于尺度不变特征变换(SIFT)和粒子滤波(PF)的目标跟踪算法在目标被完全遮挡期间，会使目标模型的特征点全部被删除而不被添加，因此无法正常工作。针对这一问题，本文引入了自适应更新目标模型和目标匹配。具体方法是采用SIFT和PF的目标跟踪方法，采用随机样本一致性(RANSAC)排除错误匹配，由于跟踪对象丢失，在建立候选对象模型时停止更新目标模型，采用k维树(k-d树)优化的Best Bin First (BBF)进行目标匹配。仿真结果表明，该方法对完全遮挡后的目标重现具有较好的鲁棒性。

A 3.75-4.25GHz frequency modulated continuous wave (FMCW) radar transceiver, employing intermediate-frequency (IF) delay rather than RF beat frequency to represent distance, is implemented in 65nm CMOS for applications in ultra-wideband (UWB) band. To overcome the trade-off between wide bandwidth and high ranging resolution in the conventional FMCW radars, a dual-BPF regenerative FM demodulator and a time-to-digital converter (TDC) are utilized to achieve low power, low complexity, and fine ranging resolution. In the transmitter, a slew rate controlled relaxation oscillator and a 3-stage RF voltage-controlled oscillator (VCO) are hired to perform frequency modulation with significant power savings. In addition, a successive approximation register (SAR) logic based automatic frequency calibration (AFC) loop is placed in the transmitter to calibrate the frequencies of the oscillators for process, voltage and temperature (PVT) robustness consideration. The proposed transceiver with 3.3mW power consumption and −110dBm sensitivity, features sub-cm ranging capability, better than the conventional designs with tens of centimeters resolution.

Corona discharge on transmission lines is a common phenomenon in power systems. Long-time continuous corona discharge on lines may cause serious grid accidents. It is of great significance to effectively locate the corona discharge point. The Hilbert fractal antenna is a wide-band, small-sized antenna through which an electromagnetic wave signal generated by corona discharge can be detected. In this paper, a 5th order Hilbert fractal antenna is designed focusing on the different feeding modes of the antenna. Then the miniaturized antenna structure that can be used for corona discharge detection of transmission lines is determined.

This paper proposes a connected area algorithm for processing a line of pixels collected by linearity CCD camera at a time based on FPGA. It can be used in material sorting equipment to separate materials of different sizes. The method is based on the twice scan method of the connected area, and implemented on FPGA, called two-row scan method. It needs to save only two rows of pixels and it is only one pixel in every scan unit. Because of scanning two rows of pixels every time, the real-time performance is extremely excellent. After calculating the area of the connected area, it will be selected and removed according to the upper limit and the lower limit while the location of the material is determined by the channel division algorithm and the high speed air valve. The area error calculated by this method is less than 5%, and the material elimination rate can reach more than 90%.

Switchable chaotic systems are more suitable for applying in chaotic secure communication because of having more complex nonlinear dynamic characteristics. A switching method and its switching circuit for different fractional-order system are proposed in this paper. Through an analog switch control, the circuit can realize the switching of two different chaotic systems, which are 0.8-order and 0.9-order systems, respectively. The circuit provides more options for the application of chaos to practical engineering.

Data transmission between spacecraft and Earth-based data receiving stations is one of the vitally important subsystem for any space mission. The time interval of visibility between spacecraft and ground stations is most valuable to accomplish scheduled data transmission volume. An algorithm to enable the more effective space-based antenna during data transmission process is put forward and analyzed in detail in this paper. A series of detailed phases are formulated, which helps space mission software engineers to easily code the smart algorithm and carry out code-testing conveniently. Once this algorithm is realized in a space mission, it could help to enhance the smartness of onboard computer software and minimize the manned intervention on the ground, which meets the current demands of artificial intelligence in space.

With the increasing number of users and the complexity of services, only single communications network cannot meet its request in smart distribution grid(SDG).Therefore, heterogeneous network is an effective way to solve this situation. In this paper, a new approach of heterogeneous wireless network for SDG based on the chi-square distance is proposed and investigated. The algorithm firstly estimate weights of network attributes using analytic hierarchy process(AHP) according to different types of service which depends more on the consideration for the user side. Secondly, the CRITIC and anti-entropy weighting method are used to determine the objective weight according to the actual network parameters, and the final weight is obtained by the comprehensive weighting method based on the alignment minimization. Finally measure the chi-square distance from each candidate network to the ideal network, and the candidate network of smallest chi-square distance is the best access network.

Internet of Things (IoT) plays a significant role in facilitating our work and making ease the life of human, for the reason that it can connect a lot of embedded devices to deal with many complicated and difficult tasks. However, security of IoT is more concern because every device is connected through internet network, and eavesdroppers are ready to steal or even uncover our private data. Therefore, in this paper, we propose joint single relay and jammer selection (JSRJS) to enhance the physical layer security (PLS) of IoT. Moreover, outage probability (OP) and intercept probability (IP) as well as the system tradeoff performance (STP) for JSRJS under Nakagami-m fading channel are analyzed, and OP、IP as well as STP of JSRJS are all compared with that of the pure single relay selection (SRS), respectively. Simulation results show that the OP of JSRJS is the same as that of SRS, while the IP of JSRJS is always better than that of SRS. In addition, the STP for JSRJS is also more perfect than that of SRS. Besides, as the number of relay nodes increases, the STP of these two approaches both improve notably.
物联网(Internet of Things, IoT)可以连接大量的嵌入式设备来处理许多复杂和困难的任务，它在方便我们的工作和简化人类的生活方面发挥着重要作用。然而，物联网的安全性更受关注，因为每个设备都是通过互联网连接的，窃听者随时准备窃取甚至泄露我们的私人数据。因此，在本文中，我们提出联合单中继和干扰器选择(JSRJS)来增强物联网的物理层安全性(PLS)。分析了JSRJS在Nakagami-m衰落信道下的中断概率(OP)、截获概率(IP)和系统权衡性能(STP)，并将JSRJS的OP、IP和STP分别与纯单中继选择(SRS)进行了比较。仿真结果表明，JSRJS的OP与SRS相同，而IP总是优于SRS。此外，JSRJS的STP也比SRS的STP更完善。此外，随着中继节点数量的增加，两种方法的STP性能都有显著提高。

This paper proposes a configurable structure of time-interleaved ADC (TI-ADC) with digital blind calibration for time-variant input signal. The channel number of the TI-ADC and the corresponding digital calibration could adapt to the input frequency, which would significantly decrease the power consumption of the TI-ADC as well as reduce the complexity of the digital calibration. In the proposed structure, the input signal is firstly fed into the power detector to roughly determine the range of the input frequency. Then the TI-ADC system activates the required sub-ADC channels accordingly and the calibration module changes to adapt to the input signal. In addition, numerical simulations have been presented to demonstrate the effectiveness and superiority of the proposed structure, which shows the proposed structure could significantly decrease the power consumption of the TI-ADC module as well as the calibration module.
