[0004] However, the method of the prior art is only applicable to the capture of continuous conventional signals. When performing loop filter tracking for discontinuous burst signals, it is necessary to use a loop filter and pre-set the parameters of the loop filter. Based on this parameter, the signal in the high dynamic environment is captured
[0005] However, using prior art methods results in high computational complexity and high computational cost

A signal acquisition method, comprising: acquiring an initial frame signal group during the initial windowing period, the initial frame signal group includes at least one initial frame signal, and each initial frame signal includes: a pilot signal and a frame body, wherein, after entering the initial windowing period Start to capture signals; determine the periodic timing windowing period based on the signal data of the initial frame signal; periodically acquire the target frame signal group according to the timing windowing period, the target frame signal group includes at least one target frame signal, and the number of target frame signals And the data carried are the same as the number of the initial frame signal and the data carried. The present application can reduce the complexity of calculation and reduce the calculation cost.
Description
technical field [0001] The present application relates to the technical field of communication signals, and in particular, to a signal acquisition method, device, device, and storage medium. Background technique [0002] In the process of satellite communication, it is usually necessary to send signals from the ground to the air, or from the air to the ground, and the receiver captures and tracks the signals to realize the interaction of the signals. [0003] In the prior art, the method adopted is usually to capture by means of threshold decision comparison and track by means of loop filtering, so as to realize the capture and track of the signal by the receiver. [0004] However, the method of the prior art is only applicable to the capture of continuous conventional signals. When performing loop filter tracking for discontinuous burst signals, it is necessary to use a loop filter and pre-set the parameters of the loop filter. Based on this parameter, the signal in a high...
