Noncoherent Multiuser Communications: Multistage Detection and Selective Filtering
We consider noncoherent multiuser detection techniques for a system employing nonlinear modulation of nonorthogonal signals. Our aim is to investigate near-optimum noncoherent multiuser-detection techniques that utilize the received signal structure ...

Iterative detection and decoding for SCMA systems with LDPC codes
Sparse code multiple access (SCMA) is a promising multiplexing approach to achieve high system capacity. In this paper, we develop a novel iterative detection and decoding scheme for SCMA systems combined with Low-density Parity-check (LDPC) decoding. In
