Abstract: In a semantic communication method, input information from a transmitter may be input into a pre-trained semantic encoder to obtain semantic signals. Then, the semantic signals may be transmitted to a first channel to obtain a third semantic signal. Moreover, a transmitter-side signal processing may be performed on the semantic signals to obtain processed semantic signals. Then the processed semantic signals may be transmitted to a second channel to obtain fourth semantic signals. Further, a receiver-side signal processing may be performed on the fourth semantic signals obtain fifth semantic signals. Finally, the fifth semantic signals may be optimized and then be input into a pre-trained semantic decoder for semantic decoding to obtain first decoded information and second decoded information.
