抄録

We propose a control-channel-hopping scheme to mitigate scrambling attacks in orthogonal frequency division multiple access (OFDMA) systems. A scrambling attack can be realized by jamming specific frames after monitoring the control channel or by jamming the control channel itself. This letter details a situation in which the control channel is scattered among OFDMA subcarriers. The scattered control channel has a two-dimensional hopping sequence with a mixed order. Simulation results show that our scheme can prevent a jammer from monitoring the control channel and from attacking the channel itself.
