In this work, a novel feature extraction technique for evaluating the complexity degree of Electromagnetic Environment (EME) is proposed by utilizing the morphological pattern spectrum (MPS) based on the mathematical morphology theory. Four types of morphological operators, mean the morphological dilate, morphological erosion, morphological open and morphological close, are utilized for computing the MPS. EME signals with four complexity degree are simulated to evaluate the effectiveness of the presented method. Experimental results have demonstrated the MPS calculated by morphological erosion operator to be very effective for discriminating the complexity degree of EME.

Knowledge bases are an extremely important database for knowledge management, which is very useful for question answering, query expansion and other related tasks. However, it often suffers from incompleteness. In this paper, we propose a Three-Way Affinity Embeddings model (TWAE) to map both the entity and relationship into two vectors and consider any two of them direct interaction, and then predict the possible truth of additional facts. The basic idea is that the confidence of the additional predicted fact is determined by three-way affinities in the triplet using the latent representation of each item. Experiments show that our model performs excellent.

The edge details of the remote sensing image is key for the target detection with complex background. Traditional Canny detection operator requires human intervention, does not have the adaptive ability in the variance of Gaussian filtering and the threshold. Compound morphological smoothing replaces Gaussian filtering, can not only maintain the edge information, but also reduce noise impact. Then Otsu method can specify the threshold adaptively, the edge detected is more continuous, and can decrease the false edges. In order to extract the edges of the remote sensing image proposed an approach based on Canny edge detection operator. Finally, we refine the edge by using morphological structure element. The experimental results show that the improved Canny algorithm has a good anti-noise function and precision on image processing of remote sensing.

Acoustic Echo Cancellation (AEC) is employed in hands-free communication systems to enhance communication experience. Double-Talk Detection (DTD) plays a vital role in AEC to distinguish the far-end and near-end signals and its failure will cause the system divergence. An efficient new DTD algorithm based on the joint signal energy and cross-correlation estimation techniques is proposed in this paper to reduce the DTD faults. The proposed algorithm can provide fast DTD and enhanced system performance without increasing much more computational complexity over the conventional techniques. Simulation results show the performance improvement achieved by the proposed technique.

A new method to improve Energy Efficiency (EE) in an energy-constrained wireless relay network is presented. In this network, the source nodes transmits signals through flat fading channels to a set of intermediate relay nodes which amplify signals and then forward them to the destination through other flat fading channels. The distances among source relay and destination are considered. Since the total network energy enhancement depend on the relay energy consumption which in turn depends on the users transmit powers and the geographic of relays location, the proposal method aims to optimize relay location for improving EE with the lowest sacrifice in the Spectrum Efficiency (SE). Analytical expressions for optimal relay location with balanced EE SE are derived and fully verified by simulation results.

The performance of Orthogonal Space-Time Block Codes (OSTBC) for Multiple-Input Multiple-Output (MIMO) systems employing M-QAM transmission is investigated over independent but not necessarily identically distributed (i.n.i.d.) generalized-K fading channels with arbitrary real-valued k and m. Before this, the i.n.i.d. generalized-K fading channel has never been considered for the OSTBC-MIMO systems. Especially, the effects of the shaping parameter k on the OSTBC-MIMO system performance are unknown. Specifically, we investigate mainly the significance of the shaping parameter k on the OSTBC-MIMO system performance in terms of the average Symbol Error Probability (SEP) and Shannon capacity. By establishing the system model, the Probability Density Function (PDF) of the equivalent Signal to Noise Ratio (SNR) is derived. Then, the closed-form expressions of such performance metrics are obtained successively. Finally, Numerical results prove that the derived expressions are validated via a set of Monte-Carlo simulations and the implications of the shaping parameter k on the overall performance are highlighted.

Implementation of ECG signal processing algorithms for removing baseline wander and electromyography (EMG) interference is proposed in this paper. First, Moving Average Filter (MAF) is used to remove the baseline wanders in ECG signal. Then the EMG components are detected and canceled by the Empirical Mode Decomposition (EMD). The Texas Instruments (TI) produced ADS1298 is chose to be the Analog Front-End (AFE) ECG capture chip which provides 8 measurement channels. The ARM series chips of STMicroelectronics produced STM32F429ZI is used as the computing core of signal processing which has operation frequency of up to 180MHz and is suitable for a large amount of data calculation as well as peripheral interface control.

A network coding scheme employing nonbinary low density parity check (LDPC) product code with signal space diversity (SSD) is proposed in this paper. The scheme is based on a multiple access relay channel with two users, one relay and one base station. Rotated modulation and component interleaving are introduced in this scheme to realize SSD so that it can enhance the bit error rate (BER) performance for the scheme. Simulation results indicate that the proposed scheme significantly outperforms the conventional binary scheme by 1.9dB in Rayleigh fading channel. Moreover, it also proves that the rotated modulation and component interleaving play an important role in improving the BER performance of the nonbinary LDPC product code.

To increase accuracy of frequency-domain visual attention model, an improved Hyper complex Fourier Transform (HFT) algorithm is proposed. Firstly, the coefficients of the input hyper complex image were well designed. Real coefficient was adjusted intensity feature, and three imaginary coefficients were adjusted L, a, b color channels. Secondly, the 2-D signal was reconstructed by the original phase and filtered amplitude spectrum images, and a series of saliency maps were obtained. Finally, regarding the saliency maps as the density distribution function, the spatial contrast function was employed to generate the optimal saliency map. Experimental results show that the average AUC value of the proposed method is 0.8649, and F-measure achieves to 0.8274, which is better than related algorithms.

The migration of virtual router has attracted a lot of attention from researchers in the new network architecture field, due to the potential to cope with emerging challenges, such as energy consumption and resource fragmentation problem. In this paper, we focus on general virtual router architecture VRSM (Virtual Router Supporting Migration), composed by a cluster of servers. Compared with other architectures, VRSM introduces intelligently interface plane, management switch and data switch. The interface plane is used to switch data traffic to new forward instances and other two switches can guarantee bandwidth separation between migration traffic and data traffic in migration process. Based on VRSM architecture, we put forward a migration strategy DMVR (Dynamic Migration of Virtual Router), which can dynamically migrate a virtual router instance from one physical server to another without disrupting the network topology. Our experiment shows that DMVR strategy results in minimal impact in the data plane and brief downtime in the control plane.
