摘要:In this paper, blind source separation (BSS) techniques based on time–frequency (t–f) distributions are proposed for multi-sensor and mono-sensor scenarios. The proposed schemes use t–f filtering and high-resolution t–f distributions to extract source signals that have ...

摘要:Leakage power dissipation is a serious concern in deep nanometer devices. 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...

摘要:The finite-time stability problem of discrete switched singular positive systems (DSSPSs) is investigated in this paper. 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...

摘要:Two electronic circuits are designed according to the dynamical model of a harmonically forced system with clearances by both conventional approach and SC-CNN strategy. Dynamics of the piecewise smooth mechanical system, in low forcing frequency domain, is investigated by double-...

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...

摘要:In this paper, we introduce an efficient demosaicking method based on an advanced nonlocal mean (NLM) filter using adaptive weight with consideration of both neighborhood similarity and patch distance. The to-be-interpolated missing color information is considered to be populated...

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...

摘要:A new technique for designing FIR filters where the desired frequency response is a smoothed rectangular function is proposed. Instead of choosing a suitable window in time domain, we will directly try smoothing the ideal desired response in frequency domain. The impulse response...

摘要:In this paper, we discuss a method to protect satellite signals from strong time-varying interferers. Time-domain, transform-domain, and space-domain algorithms have been widely used for interference suppression. However, when used under high dynamic conditions, these method...

摘要:The fractional tap-length least mean square adaptive algorithm exhibits robustness and low complexity in adaptive filter design. This algorithm employs one parameter \(\gamma \) , the tap-length adaptation step size, to balance convergence rate and steady-state tap-length fluctua...
