WebApr 9, 2024 · An essential precondition for the effective use of low-frequency spread-spectrum acoustic signals is their synchronous acquisition. Due to the low bit rate that low-frequency spread-spectrum signals have, the length of the spreading spectrum code and the number of intra-chip carriers need to be precisely designed to balance the acquisition … WebY = fftshift (X) 通过将零频分量移动到数组中心，重新排列傅里叶变换 X 。. 如果 X 是向量，则 fftshift 会将 X 的左右两半部分进行交换。. 如果 X 是矩阵，则 fftshift 会将 X 的第 …
