Channel estimation method and system and electronic equipment

The invention provides a channel estimation method and system and electronic equipment, and belongs to the technical field of communication. De-noising the channel initial solution by using a pre-trained channel de-noising device, and carrying out closed-form solution solving on the de-noised channel initial solution; wherein a corresponding real channel is generated through the channel simulation generator, noise adding is carried out to generate a corresponding channel data set, channel data samples with different noises in the channel data set are utilized to train the neural network model, and a trained channel de-noising device is obtained. According to the method, one iteration step is realized through a channel de-noising device realized through a deep neural network, the neural network only undertakes a de-noising function, and a single neural network can process different tasks; in different tasks, the same channel de-noising device can also be used; the number of iterations can be adjusted in a targ
