Algorithm 1 Expert Trajectory Generation Algorithm (ETGA)

Input: Time-frequency matrix RF (N*M). Output: Expert selection sequence ESS (1*M). initialize: ESS = zeros(1,M); Consecutive unjammed channel start timeslot S1 = 1; Consecutive unjammed channel end timeslot S2 = TL. while min(ESS) == 0 do    J = zeros(N,1)    for ii = 1:N do      if sum(RF(ii,S1:S2) > 0) == 0 then         J(ii) = S2+1;      else         J(ii) = find(RF(ii,S1:S2) > 0,1)+S1−1      end if    end for    [M,N] = max(J);    ESS(S1:M−1) = N*ones(M−S1,1);    S1 = M; end while
