    The correlation property of pulse position modulation (PPM) sequences for non-crosstalk sonar systems is analyzed. To eliminate ultrasonic crosstalk, normally each ultrasonic transducer is assigned a coded excitation signature in the transmission and then the code is identified using a correlation match in the receiver. Therefore, the correlation property is very important for the excitation seque... View full abstract»

    This paper addresses the issue for filtering noisy contaminated discrete chaotic signals. A modified cubature Kalman filter combined with QR decomposition is proposed for estimating a nonlinear discrete system. Simulation results show the proposed method can effectively reduce noise on discrete chaotic signals. In comparison with other Kalman filters, the proposed method has a better filtering per...

    Empirical mode decomposition (EMD) is a data driven processing algorithm, which applies no predetermined filter. It is able to perfectly analyze the nonlinear and nonstationary signals. In EMD decomposition processing, the mean envelopes is directly subtracted from the signals. This processing may bring a problem that the trend of the signal change is changed in different parts. In this work, we p... View full abstract»
