A Novel K-Repetition Design for SCMA
Ke Lai, Zilong Liu, Jing Lei +3
This work presents a novel K-Repetition based HARQ scheme for LDPC coded uplink SCMA by employing a network coding (NC) principle to encode different packets, where K-Repetition is…
Analyzing Uplink Grant-free Sparse Code Multiple Access System in Massive IoT Networks
Ke Lai, Jing Lei, Yansha Deng +2
Grant-free sparse code multiple access (GF-SCMA) is considered to be a promising multiple access candidate for future wireless networks. In this paper, we focus on characterizing t…
Hybrid Codeword Position Index Modulation for Sparse Code Multiple Access System
Ke Lai, Jing Lei, Lei Wen +3
In this paper, a novel variation of codeword position index based sparse code multiple access (CPI-SCMA) system, which is termed as hybrid codeword position index modulated sparse…
Codeword Position Index based Sparse Code Multiple Access System
Ke Lai, Lei Wen, Jing Lei +3
In this letter, a novel variation of sparse code multiple access (SCMA), called codeword position index based SCMA (CPI-SCMA), is proposed. In this scheme, the information is trans…
