Channel estimation and equalization design method and system

The invention provides a channel estimation and equalization design method and system, and relates to the technical field of wireless communication, received data is subjected to time synchronization, cyclic prefix removal and OFDM demodulation at a receiving end, then is processed by a channel estimation and equalization module, is decoded by a channel, and finally outputs received bits; the channel estimation and equalization module comprises three parts: a data merging part, a real part and imaginary part splitting part, a channel estimation and equalization deep convolutional neural network and a mask; when each path of data is input into the module, the data are combined, and then a real part and an imaginary part of the combined data are split; inputting the data into a channel estimation and equalization deep convolutional neural network to obtain data after channel estimation and channel equalization; according to the method and the device, the QAM data is input into the QAM module, then the QAM data
