Joint Power and Bit Allocation for Precoded Massive MIMO Channels
Shuiyin Liu, Amin Sakzad
This work addresses the joint optimization of power and bit allocation in precoded large-scale n x n MIMO systems with discrete input alphabets, specifically QAM constellations. We…
CRYSTALS-Kyber With Lattice Quantizer
Shuiyin Liu, Amin Sakzad
Module Learning with Errors (M-LWE) based key reconciliation mechanisms (KRM) can be viewed as quantizing an M-LWE sample according to a lattice codebook. This paper describes a ge…
Lattice Codes for CRYSTALS-Kyber
Shuiyin Liu, Amin Sakzad
This paper describes a constant-time lattice encoder for the National Institute of Standards and Technology (NIST) recommended post-quantum encryption algorithm: Kyber. The first m…
Fast Decoding of Low Density Lattice Codes
Shuiyin Liu, Yi Hong, Emanuele Viterbo +2
Low density lattice codes (LDLC) are a family of lattice codes that can be decoded efficiently using a message-passing algorithm. In the original LDLC decoder, the message exchange…
Guaranteeing Positive Secrecy Capacity with Finite-Rate Feedback using Artificial Noise
Shuiyin Liu, Yi Hong, Emanuele Viterbo
While the impact of finite-rate feedback on the capacity of fading channels has been extensively studied in the literature, not much attention has been paid to this problem under s…
Artificial Noise Revisited
Shuiyin Liu, Yi Hong, Emanuele Viterbo
The artificial noise (AN) scheme, proposed by Goel and Negi, is being considered as one of the key enabling technology for secure communications over multiple-input multiple-output…
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…
Decoding by Sampling: A Randomized Lattice Algorithm for Bounded Distance Decoding
Shuiyin Liu, Cong Ling, Damien Stehlé
Despite its reduced complexity, lattice reduction-aided decoding exhibits a widening gap to maximum-likelihood (ML) performance as the dimension increases. To improve its performan…
