In this paper, we propose a very large scale integration design method for a large-scale multiple-input multiple-output detection algorithm. Our design uses a modified version of the Successive Over Relaxation (SOR) method, which substantially reduces the highly computational complexity of data detection and achieves the near-optimal performance. We use a reconfigurable Processing Elements Array (PEA) to compute matrix-vector or matrix-matrix in SOR Method, which reduces the complexity of linear data detection. Then we implement our design on Xilinx Virtex-7 FPGA and the experimental results show that SOR method has a superior performance over conventional methods.

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.

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.

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.

In this paper, closed form outage probability is derived for cognitive amplify-and-forward (AF) relaying system in a spectrum sharing environment for a moving end mobile users. The end users can move at high vehicular speeds which cause dynamic multipath fading and a high Doppler shift. The transmit power of the secondary network is governed by the maximum interference power that the primary network's receiver can tolerate. In the proposed model, the channel between relay to destination is modeled as Nakagami-m fading channel, m <; 1 that is most suitable for modeling channel fading at high mobility scenarios whereas the other communication links are modeled by Rayleigh distribution. The impact of the PU location on the OP performance is studied also.

In practice, channel state is complicated and changing in the mobile communication environment. For the downlink asymmetric Two-Way Relay Channels (TWRC), we presented a joint Hierarchical Modulation and Physical-Layer Network Coding (HM-PNC) scheme. Firstly, a two-way relay communication system model consisting of the source and relay nodes using 2/4-QAM hierarchical modulation is constructed. Secondly, the Physical layer Network Coding (PNC) demodulation and mapping rules at the relay node is presented, the formula for calculating the end-to-end Bit Error Rate (BER) under the Additive White Gaussian Noise (AWGN) is derived as well. Finally, the simulation results are presented which verify the theoretical analysis results. Compared with PNC using the traditional 4QAM modulation technique, the advantage of the hierarchical modulation is made use of to ensure a higher data rate in the better link and to take into account the reliability of worse link.

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.

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.

In order to solve the problem of feedback link overhead in MIMO-OFDM system, and improve the transmission efficiency, a limited feedback method based on KL domain is proposed in this paper. In this method, the state information which is obtained from the channel estimation performed in KL domain sparse at the receiving end. Thereby a small amount of linear measurements are obtained which represents the total channel state information, Then these measurements are fed back to the transmitting end. In the transmitter, the channel state information is reconstructed through orthogonal matching pursuit algorithm. The simulation results show that the proposed limited feedback based on KL (Karhuner-Loeve) domain method can achieve full channel state feedback effect and decreases the overhead in the feedback link.

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.
