In cooperative communications, spatial channel diversity introduced by scattered locations of cooperating nodes can be exploited to enhance transmission security. In this paper, we propose a secure cooperative orthogonal frequency division multiplexing (OFDM) transmission scheme with the help of multiple relay nodes. For each relay, the wireless channels related to the destination and the eavesdropper are independent of each other, leading to different achievable rates over each subcarrier. In… CONTINUE READING
