Web摘要提出了一种新的基于分数傅里叶变换(Frft)域的自适应算法,该算法将基于统计和ffft相结合的检测方法结合起来,对线性调频(Lfm)信号具有良好的能量集中特性,并通过计算光谱峰度(Sk)来确定最优变换角。 WebComputes the one dimensional Fourier transform of real-valued input. The FFT of a real signal is Hermitian-symmetric, X [i] = conj (X [-i]) so the output contains only the positive frequencies below the Nyquist frequency. To compute the full output, use fft () Note Supports torch.half on CUDA with GPU Architecture SM53 or greater.

WebJun 1, 2011 · The standard Fourier transform is a special case of the FRFT with a rotation angle α = π / 2. 2. F 0 is the identity operator, i.e., F 0 ( x ( t)) = x ( t). The same can be stated for F 2 π. 3. The FRFT is a linear operator, i.e., F α …
