The proposed schemes use t–f filtering and high-resolution t–f distributions to extract source signals that have ...

Low power design methodology is often adopted in VLSI circuits and systems to minimize power; however, this is achieved at the cost of performance penalty. In this paper, we first review the existing c...

First, the concept of finite-time stability for DSSPSs is proposed, and a necessary and sufficient condition of finite-time stability for DSSPSs under arbitrar...

Shahnawazuddin , Gayadhar Pradhan 来源：[J].Circuits, Systems, and Signal Processing(IF 0.982), 2017, Vol.36 (6), pp.2315-2340 摘要：Detecting the vowel regions in a given speech signal has been a challenging area of research for a long time. A number of works have been reported over the years to accurately detect the vowel regions and the corresponding vowel onset points (VOPs) and vowel end points (VEPs...

The to-be-interpolated missing color information is considered to be populated...

Selvaganesan 来源：[J].Circuits, Systems, and Signal Processing(IF 0.982), 2017, Vol.36 (9), pp.3761-3777 摘要：In finite scattering propagation environment, when the number of scatterers is very small compared to the number of base station antennas and users in the cell and if the same scatterers are shared by all users, then the correlation among the users increases. Hence, the high-dime...

Instead of choosing a suitable window in time domain, we will directly try smoothing the ideal desired response in frequency domain. The impulse response...

Time-domain, transform-domain, and space-domain algorithms have been widely used for interference suppression. However, when used under high dynamic conditions, these method...
