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.

Performance on ICI Self-Cancellation in FFT-OFDM and DCT-OFDM System
Journal of Function Spaces, 2015 In orthogonal frequency division multiplexing (OFDM) system, the existence of frequency offset in AWGN channel affects the orthogonality among the subcarriers and consequently introduces the intercarrier interference (ICI). The paper investigates new ICI
