Title:
MULTIPATH SEPARATION METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/177766
Kind Code:
A1
Abstract:
The present application provides a multipath separation method and device, and a storage medium. The multipath separation method comprises: extracting frequency domain response characteristics of received reference signals in at least two different frequency bands; constructing a Toeplitz matrix corresponding to each frequency band; combining the Toeplitz matrixes corresponding to the at least two different frequency bands; performing singular value decomposition on the synthesized Toeplitz matrix, and determining a signal space matrix and a noise space matrix according to the decomposed matrix; constructing multiple frequency domain response vectors according to frequency domain response characteristics of local signals which have different delays and are the same as the received reference signals; and obtaining an inner product of each of the multiple frequency domain response vectors and the noise space matrix, comparing the inner products with a preset threshold, and then determining the delay corresponding to each frequency domain response vector in multiple frequency domain response vectors which satisfy the preset threshold to be a delay of one path in the multipath.
