Verification-Based Interval-Passing Algorithm for Compressed Sensing
Xiaofu Wu, Zhen Yang
We propose a verification-based Interval-Passing (IP) algorithm for iteratively reconstruction of nonnegative sparse signals using parity check matrices of low-density parity check…
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…
Turbo DPSK in Bi-directional Relaying
Weijun Zeng, Xiaofu Wu, Zhen Yang
In this paper, iterative differential phase-shift keying (DPSK) demodulation and channel decoding scheme is investigated for the Joint Channel decoding and physical layer Network C…
Compressed Sensing with Incremental Sparse Measurements
Xiaofu Wu, Zhen Yang, Lu Gan
This paper proposes a verification-based decoding approach for reconstruction of a sparse signal with incremental sparse measurements. In its first step, the verification-based dec…
Polar Lattices: Where Arıkan Meets Forney
Yanfei Yan, Cong Ling, Xiaofu Wu
In this paper, we propose the explicit construction of a new class of lattices based on polar codes, which are provably good for the additive white Gaussian noise (AWGN) channel. W…
