    The emerging theory of compressed sensing (CS) not only enables the reconstruction of sparse signals from a small set of random measurements, but also provides a universal signal demodulation approach at sub-Nyquist sampling rate. Compressed signal demodulation is particularly suitable for impulse ratio ultra-wideband (IR-UWB) communications where Nyquist sampling is a formidable challenge. In thi... View full abstract»

    Chaos characteristic analysis of the phase-locked loop (PLL) synthesizer has been made in this paper based on the phase model of it, and we conclude the state equation of this model and the condition when the system becomes chaos. Because the parameters of the PLL synthesizer will be changed when the FH radio switch the frequency, the system may turn to be chaos caused by the parameters of it meet... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (224 KB) | HTML iconHTML

    We report synchronization and amplitude death phenomenon in identical time-delay chaotic systems. Theoretical analysis and numerical simulations show that complete synchronization, antisynchronization, and amplitude death are induced simultaneously in different state variables of an infinitedimensional response system. It overcomes some limitations of the previous work where coexistence of synchro... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (280 KB) | HTML iconHTML

    Passive techniques such as barriers, silencers and isolation are bulky, costly and ineffective at low frequencies. Active cancellation of noise was presented because of these problems. In this paper, we want to investigate the uses of neural networks in active noise control (ANC). Feed-forward and recurrent neural networks are compared for active cancellation of sound noise. In order to compare th... View full abstract»

    To solve the problem that motor data does not have intuitive semantics, and it is hard to get complete fault information as the signal kinds monitored is more and its complexity is higher than before, this paper proposes a fault diagnosis method based on Ontology and Particle Swarm-Immune Optimization algorithm. It first creates an ontology library using the expert knowledge. Secondly, it extends ... View full abstract»

    This study aims to provide general technicians who manage pests in production with a convenient way to recognize insects. A viable scheme to identify insect sounds automatically is proposed by using sound parameterization techniques that dominate speaker recognition technology. The acoustic signal is preprocessed, segmented into a series of sound samples. Mel-frequency cepstrum coefficient(MFCC) i... View full abstract»

    The performance of the directions-of-arrival (DOA) estimation is a strong function of array geometry configuration. Nowadays the Uniform Circular Arrays (UCA) arouse more and more attention due to their remarkable characteristics. In this paper, we derive the ambiguity formulation, the resolution and Cramer-Rao Lower Bound (CRLB) functions on the basis of the study of data model, the radiation pat... View full abstract»

    The single precision in the computer is composed of two parts: the mantissa and the exponent. which are expressed by the limited binary bits. During adding on the single precision, the smaller one should shift to line up the decimal points, If the mantissa of the smaller one exceeds the range of registers, truncating or rounding off will be executed and cause losing precision. As far as the serial... View full abstract»
