Embodiment Construction
[0031] The specific calculation process of the complex-valued structure optimization algorithm proposed by this patent will be further described below in conjunction with the accompanying drawings and specific embodiments of the present invention.
[0032]In the realization of signal modulation identification, artificial neural network is a relatively common method. For the processing of signal modulation identification, the forward complex-valued neural network is an efficient means. Forward complex-valued neural network has attracted the attention of scholars due to its fast learning and ability to directly process complex signals, and there are more and more researches related to it. In some application areas such as radar signal processing, medical image processing, channel state prediction, EEG, etc.
[0033] For the forward complex number neural network, how to quickly determine the network structure and network parameters is a big problem. The complex-valued structure ...
