In this paper, a multi-user massive multiple-input and multiple-output (MIMO) uplink system is considered, in which multiple single antenna users communicate with a target BS equipped with a large antenna array. We assume both the BS and K users have no knowledge of channel statement information. For such a system, by utilizing the unique factorization of three-way tensors, we proposed a parafac-based blind channel estimation and symbol detection scheme for the massive MIMO system, the proposed system can ensure the unique identification of the channel matrix and symbol matrix in a noise-free case. In a noisy case, a novel fitting algorithm called constrained bilinear alternating least squares is proposed to efficiently estimate the channel matrix and symbols. Numerical simulation results illustrate that the proposed scheme has a superior bit error ratio and normalized mean square error performance than traditional least square method. In addition, it has a faster convergence speed than typical alternation least square fitting algorithm.

With the rapid development of smart phones, mobile advertising has taken up more than half of the advertising market and has great potential in the future. At present, there are many mature researches on the conversion rate of search advertising, but few studies have been done on the conversion rate of mobile APP advertising. This paper studies the preliminary data of Tencent's first social advertising algorithm competition and provides a method for prediction of mobile APP advertising conversion rate based on machine learning.

The single sample per person(SSPP) face recognition is one of the most essential problems of face recognition. Moreover, the testing samples are typically corrupted by nuisance variables such as expression, illumination and glasses. To address this problem, plenty of methods have been proposed to surmount the adverse effect of variances to testing samples in complex surroundings, but they are not robust. Therefor we proposed the Single sample per person face recognition based on sparse representation with extended generic set (SRGES). First, a set of general sample set were introduced, and the variation information of generic face samples set was extracted and extended to the single training sample set. Then, reconstruction error of testing sample is generated on training samples set by sparse representation model. Finally, the recognition is achieved depending on this sparse reconstruction error. The experimental results on the AR database, Extended Yale B database, CAS-PEAL database and LFW database displayed that the proposed algorithm is robust to variation feature for SSPP face recognition, and outperforms the state-of-art methods.

A Coarse-Grained Reconfigurable Architecture called RASP2.0 is proposed in this paper for communication baseband signal processing. Based on the pipeline bubbles theory, the reconfigurable data path is divided into the data flow between processing elements and the data interaction between reconfigurable arrays and memory structure. To reduce the data transmission delay, the data flow features are summarized based on the locality and lifetime of data. By employing a parallel memory structure combined with the DLT-based data updating strategy, the access performance is improved by 33% on average compared with RASP1.0. As a result, the reconfigurable system presents more performance advantages and flexibility than other similar platforms.

Despite recent advances, including hierarchical and sound clustering techniques, perceptual audio rendering technique remains a high challenge for complex virtual scenes with thousands of sound sources due to its high computation cost. In the paper, we first present a spatial-frequency measurement based approach to generate recursive cluster for multiple sound source. This method can handle more than two times the number of sources on consumer 3D audio hardware, with minimal decrease in audio quality. The perceptual pilot was then studied which indicates its necessity to increase the number of different clusters of visible sound source. We present a sound categories based cost metric using this indication. The proposed method preforms well for rendering thousands of sound sources on a workstation.

The concept of metric dimension was proposed to model robot navigation where the places of navigating agents can change among nodes. The metric dimension md(G) of a graph G is the smallest number k for which G contains a vertex set W such that |W| = k and every pair of vertices of G possess different distances to at least one vertex in W. In this paper, we demonstrate that md(HDN1(n)) = 4 for n ≥ 2, this indicates that in this type of hex derived sensor networks, the least number of nodes needed is 4 for locating any other node in such a sensor network.

With the gradual development of high proportion renewable energy access to distribution network and smart grid, the coupling of physical and information processes in distribution networks are becoming more and more closely coupled. It is a typical Cyber Physical System (CPS). The sequential characteristics of distribution network and the time discrete characteristics of communication systems make the research of distribution network CPS more complex. This paper aims at the dynamic process of distribution network CPS. On the basis of CPS's perception of the environment, explain the applicability and make an analysis from the aspect of CPS integration modelling and large scale simulation of distribution network.

In this paper, a joint optimization scheme of data gathering and charging is proposed to achieve the energy balance for wireless rechargeable sensing networks (WRSNs) consisted of one static base sink, one mobile charger sink and many sensor nodes. In this scheme, the urgent degree of charging is designed by considering the residual life time of nodes and the number of neighbor nodes to help determine anchor points in charging plan. In addition, a metric of forwarding cost value is proposed to construct the network topology targeting at the least cost routing path by considering the energy state, distance between nodes and child nodes number. Moreover the performance of WRSNs is analyzed in terms of average energy and energy stand deviation of each node. Simulation results show that WRSNs can achieve good performance by employing the proposed joint optimization scheme.
