A new memory based LT encoding scheme is proposed to improve communication reliability and decrease latency at the same time. The robust Soliton distribution (RSD) is shifted as the output symbol degree distribution in the proposed method. The input symbol degree distribution is also changed based on memory. Analysis shows the proposed method has faster decoding convergence speed than the conventional memory based LT code. Simulation results validate the analysis and show BER performance. Compared with regular LT code and the conventional memory based LT code, the proposed method has better BER performance.

A new miniaturized triple-frequency microstrip antenna is proposed. The proposed antenna mainly consists of two circular rings, a circle, a horizontal rectangular strip, three vertical rectangular strips and a defected ground plane. The proposed antenna can generate three separate impedance bandwidths to cover all the 2.4/5.2/5.8GHz Bluetooth/WLAN (Wireless Local Area Network)/RFID (Radio Frequency Identification Devices) operating bands and the 2.5/ 3.5/5.5GHz WiMAX (Worldwide Interoperability for Microwave Access) operating bands. By adding a vertical rectangular strip and a circle along the microstrip direction, the antenna excites two resonant modes and is with miniaturized structure. Because of the introduction of the cambered ground plane with a circular defect, the third wide band with better impedance matching is obtained. Result shows the proposed antenna has good performance.

This paper presents a new fuzzy clustering algorithm to solve the problem that the fuzzy c-means (FCM) clustering algorithm has a poor accuracy of clustering. The adopted methodology used the minimum support tree principle to get the initial clustering center and augmented lagrange multiplier method to solve the problem of noise sensitive of the FCM algorithm. Besides, the Hopfield neural network is used to calculate the cluster center and complex synaptic neural network is used to obtain the membership grades. In the experiment, the proposed algorithm is simulated and compared with the commonly used clustering algorithm. The clustering accuracy is higher than that of other algorithms. The analysis proves that the algorithm has universal guiding significance in theory and engineering practice.

Complementary pair has ideal aperiodic auto-correlation property and then may reduce the peak-to-mean envelope power ratio (PMEPR) of orthogonal frequency division multiplexing (OFDM) systems to 3dB. However, for some OFDM systems requiring vacant direct current (DC) subcarrier, the ideal aperiodic auto-correlation property of complementary pair will be damaged, which leads to the increased PMEPR. In this paper, the modified sequences are designed on the basis of zero-inserting operation and combination operation to original complementary pair, respectively. The proposed methods may maintain ideal aperiodic auto-correlation property of original complementary pair even if it is employed in OFDM systems with vacant DC subcarrier. Both theoretical analyses and simulation results show the availability of the presented algorithms, and the expectable PMEPR-3dB property may be obtained.

In this paper, a miniaturized, self-actuated, energy selective spatial filter is designed for achieving field intensity dependent electromagnetic (EM) protection in a working frequency band. The spatial filter is periodic with each unit loaded with four microwave nonlinear devices. The dimension of the unit is in size of λ/16 and is ultrathin. Structural design, mechanism of operation are presented and discussed. A full-wave simulation is carried out for obtaining the transmission characteristic of the spatial filter. Results show that the received field intensity by using the spatial filter can be well controlled with a variable power loss from 0.1 dB up to 24 dB, and the spatial filter has a stable transmission characteristic to different incident angles. Therefore, the spatial filter is able to distinguish small signals from strong incident waves and can be utilized in EM protection against high power microwaves.

To detect compromised sensor nodes in wireless sensor network, one main way is to detect their sensing data with the cooperation of their neighbor nodes because of spatial correlation. In most time, these neighbor nodes are equally treated. However these neighbor nodes are different in the view of temporal correlation. To address this, we discuss the differential cooperation of neighbor nodes. In this paper, we proposed distance-differential cooperation and correlation-differential cooperation, and discuss their advantage and disadvantage with the cases study. Our discussion shows that differential cooperation is capable of improving the capability of detecting compromised sensor nodes.

In the industrial environments, the efficient automatic control of terminal devices depends on the changing of reception data and customized rules. As the development of Industrial Internet of Things (IIoT), more and more industrial data can be achieved to generate the big data of IIoT. Therefore, efficient matching and processing of dynamic IIoT big data and customized rules becomes increasingly important. This paper presents a two-level reasoning method in improving performance of rule engine. The first level uses a decision function trained by Support Vector Machine (SVM) to classify reported data from sensors based on the semantic data interface. In this stage, the useless data is filtered in order to reduce subsequent process. In the second level an improved RETE, in this paper is called SVM_RETE algorithm for matching rules and performing actions is presented to increase efficiency of reasoning processing. The proposed scheme is performed in a practical industrial environment. The experiment results show that the method can be performed efficiently and flexibly when massive data is involved.

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.

As an important part of future wireless communication technology, D2D communication can reduce the pressure of increasing demand for limited radio resources and improve the performance of wireless communication. To further promote the transmission efficiency of D2D communication, researchers combine social networks with it to establish a two-tier model that typically includes social domain and physical domain. This paper presents a personal trajectory based social aware content share solution to D2D communication. Personal trajectory data contains both physical and social information which contacts two domains of the model. The solution of this paper also considers the classification of share contents. Simulation results show that proposed solution improve the performance of D2D transmission.
