Encryption Over the Air: Securing Two-Way Untrusted Relaying Systems Through Constellation Overlapping.
IEEE Transactions on Wireless Communications(2018)
摘要
This paper proposes a novel technique called constellation overlapping to secure two-way untrusted relaying systems. We first consider the symmetric case where two terminal users adopt the same modulation type. For this case, a truncated-channel-inversion-based approach is developed to make the signals from different users experience the same equivalent channel, thereby realizing full constellatio...
