Practical Secrecy using Artificial Noise
Shuiyin Liu, Yi Hong, Emanuele Viterbo
In this paper, we consider the use of artificial noise for secure communications. We propose the notion of practical secrecy as a new design criterion based on the behavior of the…
Practical Secrecy: Bridging the Gap between Cryptography and Physical Layer Security
Shuiyin Liu, Yi Hong, Emanuele Viterbo
Current security techniques can be implemented either by requiring a secret key exchange or depending on assumptions about the communication channels. In this paper, we show that,…
Decoding by Sampling - Part II: Derandomization and Soft-output Decoding
Zheng Wang, Shuiyin Liu, Cong Ling
In this paper, a derandomized algorithm for sampling decoding is proposed to achieve near-optimal performance in lattice decoding. By setting a probability threshold to sample cand…
Proximity Factors of Lattice Reduction-Aided Precoding for Multiantenna Broadcast
Shuiyin Liu, Cong Ling, Xiaofu Wu
Lattice precoding is an effective strategy for multiantenna broadcast. In this paper, we show that approximate lattice precoding in multiantenna broadcast is a variant of the close…
