Abstract
A method and system for detecting FSS by a peak threshold, and a receiver include: a peak search module configured to perform peak search on a set of inputted CIR average values to obtain a set of CIR peaks; a threshold generation module configured to search for a maximum value from the obtained set of CIR peaks, obtain an FSS search threshold according to the maximum value and a preset threshold, and provide the FSS search threshold to an FSS detection module; and the FSS detection module configured to utilize the FSS search threshold to detect an FFT windowing position of a receiving antenna. The technical solutions according to the disclosure improve the protection capability from exceptions for FSS detection while reducing the detection complexity of FSS.
