In this paper, a new tensor-based subspace approach is proposed to estimate the direction of departure (DOD) and arrival (DOA) for bistatic multiple-input multiple-output (MIMO) radar in presence spatial colored noise. Firstly, received signals can be packed into third-order measurement tensor by exploiting inherent structure matched filter. Then, divided two sub-tensors, cross-covariance formulated eliminate Finally, signal constructed utilizing higher-order singular value decomposition...
The lifting scheme is well known to be an efficient tool for constructing second generation wavelets and often used design a class of biorthogonal wavelet filter banks. For its efficiency, the implementation has been adopted in international standard JPEG2000. It that orthogonality important property many applications. This paper presents how implement infinite-impulse-response (IIR) orthogonal banks by using with two steps. shown IIR can realized allpass filters Then, proposed discussed....
Wind turbines revolve in difficult operating conditions due to stochastic loads and produce massive vibration signals, which cause obstacles detecting potential fault information. To overcome this, an adaptive detection approach is presented this paper on the basis of parameterless empirical wavelet transform (PEWT) margin factor. PEWT can decompose signal into a series modes (EMs) through splitting its Fourier spectrum, using scale space method adaptively constructing orthogonal filter...
