Claim 1:
2. The dynamic power control method for resisting multi-user parameter biased aggregation in federated learning according to claim 1, wherein in step (1), the federated learning system model for resisting parameter biased aggregation comprises a transmitter network, a wireless channel, and a receiver network, the transmitter network comprises one-bit quantization , local user parameter updating portion, and user dynamic power control block, and the receiver network comprises an non-coherent energy detector;
the one-bit quantization simplifies the sign of local gradient parameters, the local user parameter updating portion is configured to realize a local updating training process of the federated learning system model, the user dynamic power control block dynamically controls the transmitted power according to the degree of contribution of each user to the convergence of the federated learning system model, so as to offset the deviation of parameter aggregation in the wireless channel, and the non-coherent energy detector uses interference to perform aggregation, and compares energy on two different sub-carriers to detect an aggregation value of all the users, so as to realize data recovery of the receiver network more efficiently.
