Fourier transform is the classical tool for performing spectral analysis of a short-duration signal and fast Fourier transform (FFT) is the widely used algorithm for achieving the same with a high degree of computational efficiency. Recently a “single bin Fourier transform algorithm” has been proposed by the present authors, which is designed to compute the spectral amplitude and phase of a single...
We present an enhanced CSI feedback scheme for FD-MIMO systems based on a linear combination codebook. To reduce codebook search complexity, an efficient codebook search method is also provided. Both capacity-based and system-level performance evaluations of the proposed scheme are conducted and the performance is compared with the Kronecker product codebook based scheme. The proposed linear combination...
This paper proposes to use discrete Fourier transform (DFT) and discrete wavelet transform (DWT) methods to schedule grid-scale energy storage systems to mitigate wind power forecast error impacts while considering energy storage properties. This is accomplished by decomposing the wind forecast error signal to different time-varying periodic components to schedule sodium sulfur (NaS) batteries, compressed...
