Joint Near Field Uplink Communication and Localization Using Message Passing-Based Sparse Bayesian Learning
Fei Liu, Zhengdao Yuan, Qinghua Guo +3
This work deals with the problem of uplink communication and localization in an integrated sensing and communication system, where users are in the near field (NF) of antenna apert…
Matrix Factorization Based Blind Bayesian Receiver for Grant-Free Random Access in mmWave MIMO mMTC
Zhengdao Yuan, Fei Liu, Qinghua Guo +3
Grant-free random access is promising for massive connectivity with sporadic transmissions in massive machine type communications (mMTC), where the hand-shaking between the access…
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…
