description The invention provides an OFDM channel estimation method based on a depth feature fusion network, which comprises the following steps: S1, inserting a pilot into an original transmission signal; S2, the serial data stream of the transmission signal obtained in the step S1 is changed into a parallel data stream, and the transmission signal is OFDM modulated by the IDFT; 3, chan a transmission signal from a parallel data stream to a serial data stream; Transmitting to a receiving end via an OFDM channel; 4, aft receiving that transmission signal, the receive end changes the transmission signal from the serial data stream to the parallel data stream, and then demodulates the transmission signal by using the DFT; 5, chan a transmission signal from a parallel data stream to a serial data stream, inputting that transmission signal into a channel estimation model of a depth characteristic fusion network, and output the transmission signal fused by the channel estimation model; The invention can effectively recover t
