Message Passing Based Structured Sparse Signal Recovery for Estimation of OTFS Channels with Fractional Doppler Shifts
Fei Liu, Zhengdao Yuan, Qinghua Guo +2
The orthogonal time frequency space (OTFS) modulation has emerged as a promising modulation scheme for high mobility wireless communications. To enable efficient OTFS detection in…
Iterative Detection for Orthogonal Time Frequency Space Modulation with Unitary Approximate Message Passing
Zhengdao Yuan, Fei Liu, Weijie Yuan +3
The orthogonal-time-frequency-space (OTFS) modulation has emerged as a promising modulation scheme for high mobility wireless communications. To harvest the time and frequency dive…
Joint Channel-Estimation/Decoding with Frequency-Selective Channels and Few-Bit ADCs
Peng Sun, Zhongyong Wang, Robert W. Heath +1
We propose a fast and near-optimal approach to joint channel-estimation, equalization, and decoding of coded single-carrier (SC) transmissions over frequency-selective channels wit…
AN-aided Secure Transmission in Multi-user MIMO SWIPT Systems
Zhengyu Zhu, Ning Wang, Zheng Chu +2
In this paper, an energy harvesting scheme for a multi-user multiple-input-multiple-output (MIMO) secrecy channel with artificial noise (AN) transmission is investigated. Joint opt…
Beamforming and Power Splitting Designs for AN-aided Secure Multi-user MIMO SWIPT Systems
Zhengyu Zhu, Zheng Chu, Ning Wang +3
In this paper, an energy harvesting scheme for a multi-user multiple-input-multiple-output (MIMO) secrecy channel with artificial noise (AN) transmission is investigated. Joint opt…
A New Combination of Message Passing Techniques for Receiver Design in MIMO-OFDM Systems
Chuanzong Zhang, Zhengdao Yuan, Zhongyong Wang +1
In this paper, we propose a new combined message passing algorithm which allows belief propagation (BP) and mean filed (MF) applied on a same factor node, so that MF can be applied…
