Low Complexity Iterative Receiver Design for Sparse Code Multiple Access
Fan Wei, Wen Chen
Sparse code multiple access (SCMA) is one of the most promising methods among all the non-orthogonal multiple access techniques in the future 5G communication. Compared with some o…
Towrad 5G Air Interface Technology: Sparse Code Muliple Access
Fan Wei, Wen Chen, Yong peng Wu +2
The fifth generation wireless networks focus on the design of low latency, high data rate, high reliability, and massive connectivity communications. Non-orthogonal multiple access…
Random Pilot and Data Access for Massive MIMO Spatially Correlated Rayleigh Fading Channels
Junyuan Gao, Yongpeng Wu, Fan Wei
Random access is necessary in crowded scenarios due to the limitation of pilot sequences and the intermittent pattern of device activity. Nowadays, most of the related works are ba…
Message-Passing Receiver Design for Joint Channel Estimation and Data Decoding in Uplink Grant-Free SCMA Systems
Fan Wei, Wen Chen, Yongpeng Wu +2
The conventional grant-based network relies on the handshaking between base station and active users to achieve dynamic multi-user scheduling, which may cost large signaling overhe…
