    Application of formant instantaneous characteristics to speech recognition and speaker identification

    HOU Li-minHU Xiao-ningXIE Juan-min
    123-127页
    查看更多>>摘要：This paper proposes a new phase feature derived from the formant instantaneous characteristics for speech recognition (SR) and speaker identification (SI) systems.Using Hilbert transform (HT), the formant characteristics can be represented by instantaneous frequency (IF) and instantaneous bandwidth, namely formant instantaneous characteristics (FIC).In order to explore the importance of FIC both in SR and SI, this paper proposes different features from FIC used for SR and SI systems.When combing these new features with conventional parameters, higher identification rate can be achieved than that of using Mel-frequency cepstral coefficients (MFCC) parameters only.The experiment results show that the new features are effective characteristic parameters and can be treated as the compensation of conventional parameters for SR and SI.

    Optimization of threshold for local spectrum sensing with energy detector

    ZHAI Xu-pingHE Hai-genZHENG Guo-xin
    132-136页
    查看更多>>摘要：Spectrum sensing is the first step of cognitive radio (CR).In this area, previous researches mostly consider distributed local nodes which are under identical channel conditions, hence uniform and fixed detection threshold is set with energy detector.However, the distributions of nodes in real environments are not quite the same.In this paper, the optimal threshold to minimize the total detection error over additive white Gaussion noise (AWGN) channel is derived firstly.Then the dynamic threshold scheme is proposed to reduce the average total detection error.Simulations have shown that, with this scheme, sensing performance is improved.

    Stress and modal birefringence of single-mode specialty optical fibers with three-stress regions

    MENG Yi-chaoWU Ming-hua
    137-142页
    查看更多>>摘要：Stress-induced birefringence and modal birefringence of single-mode specialty optical fibers with three stress regions are numerically analyzed by the vector finite element method.Stress distribution and stress-induced birefringence distribution of three kinds of optical fibers with different cross structures are presented and compared, and the influence on the stressinduced birefringence by temperature change are analyzed as well.The results show that the fibers with three-stress regions have a lower linear birefringence, which is very important for the fabrication of the circular polarization-maintaining fiber with high performance drawn from the same fiber preform by using the spinning method.

    Energy efficient clustering algorithm based on neighbors for wireless sensor networks

    ZHOU Wei
    150-153页
    查看更多>>摘要：In this paper, an energy efficient clustering algorithm based on neighbors (EECABN) for wireless sensor networks is proposed.In the algorithm, an optimized weight of nodes is introduced to determine the priority of clustering procedure.As improvement, the weight is a measurement of energy and degree as usual, and even associates with distance from neighbors, distance to the sink node, and other factors.To prevent the low energy nodes being exhausted with energy, the strong nodes should have more opportunities to act as cluster heads during the clustering procedure.The simulation results show that the algorithm can effectively prolong whole the network lifetime.Especially at the early stage that some nodes in the network begin to die, the process can be postponed by using the algorithm.
