Method and device for identification and demodulation of satellite amplitude and phase signals based on cyclic neural network |
| abstract |
The invention belongs to the technical field of satellite communication signal processing, and in particular relates to a method and device for identifying and demodulating satellite amplitude and phase signals based on a cyclic neural network. The method comprises: constructing a modulation identification and demodulation network for training sample sets and test sample sets model, use the training sample set to train the network model, and use the test sample set to check the degree of convergence of the trained network model, and save the modulation identification and demodulation network model that meets the preset convergence requirements; The target signal is preprocessed to obtain the data to be identified that is consistent with the input signal of the network model; the modulation identification and demodulation network model is used to modulate and identify the data to be identified, and the modulation identification result is used to demodulate the signal to obtain the signal bit stream data. . The invention does not need to estimate the target signal carrier-to-noise ratio, overcomes the defects of the traditional method of artificially determining the threshold and the like, has strong tolerance to signal frequency offset error and timing error, and has strong engineering application prospects. |
