Claim 4:
5. The dynamic power control method for resisting multi-user parameter biased aggregation in federated learning according to claim 1, wherein in step (4), the edge server obtains the aggregation value v, vi(n) of the ith gradient sign shown in Formula (XII):

vi(n)□ sign  (Δi(n))  (XII),

in Formula (XII), Δi(n)□ei+−ei−, ei+□|yc+(n)|22, ei−□|yc−(n)|22, ∀i, v(n)=[v1(n), v2(n), . . . , vq(n)]T is an aggregation value vector for each user recovered at the receiver, and yc+(n) and yc−(n) are superimposed symbols of given i at the receiver.
