Sphere Decoding Revisited
Zheng Wang, Cong Ling, Shi Jin +2
In this paper, the paradigm of sphere decoding (SD) for solving the integer least square problem (ILS) is revisited, where extra degrees of freedom are introduced to exploit the de…
PAC Codes for Source and Joint Source-Channel Coding
Mengfan Zheng, Cong Ling
Polarization-adjusted convolutional (PAC) codes, as a concatenated coding scheme based on polar codes, is able to approach the finite-length bound of binary-input AWGN channel at s…
Algorithms and Bounds for Complex and Quaternionic Lattices With Application to MIMO Transmission
Sebastian Stern, Cong Ling, Robert F. H. Fischer
Lattices are a popular field of study in mathematical research, but also in more practical areas like cryptology or multiple-input/multiple-output (MIMO) transmission. In mathemati…
Lattice Codes for Lattice-Based PKE
Shanxiang Lyu, Ling Liu, Cong Ling +2
Existing error correction mechanisms in lattice-based public key encryption (PKE) rely on either naive modulation or its concatenation with error correction codes (ECC). This paper…
Optimal rate-limited secret key generation from Gaussian sources using lattices
Laura Luzzi, Cong Ling, Matthieu R. Bloch
We propose a lattice-based scheme for secret key generation from Gaussian sources in the presence of an eavesdropper, and show that it achieves the strong secret key capacity in th…
Better Lattice Quantizers Constructed from Complex Integers
Shanxiang Lyu, Zheng Wang, Cong Ling +1
This paper investigates low-dimensional quantizers from the perspective of complex lattices. We adopt Eisenstein integers and Gaussian integers to define checkerboard lattices $\ma…
