Abstract
A communication method, for a receiver, including receiving a received signal, and obtaining information of an original signal according to the received signal. A transmitter obtains a transmitted signal according to the original signal. The transmitter sends the transmitted signal. The transmitted signal is changed to the received signal after passing through a channel. The transmitted signal and the received signal are correlated using a structural causal model. A number of a plurality of causal variables of a causal graph of the structural causal model and a causal structure of a causal graph of the structural causal model are determined together.
