Ergodic Capacity and Outage Performance Analysis of Uplink Full-Duplex Cooperative NOMA System
IEEE Access, 2020 We propose an uplink full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) system, where a dedicated Full-duplex (FD) relay is used to help two uplink users transmitting information to the base station.

Wireless Communications and Mobile Computing, 2003 AbstractThe 3GPP WCDMA is a widely accepted third‐generation cellular system standard. By using nonorthogonal codes for different users, the multiple access interference (MAI) can be a limiting factor for system performance, as for other CDMA systems.
