Abstract

In this paper, we propose two schemes based on a full-duplex network-coded cooperative communication (FD-NCC) strategy, namely, full-duplex dynamic network coding (FD-DNC) and full-duplex generalized dynamic network coding (FD-GDNC). The use of full-duplex communication aims at improving the spectrum efficiency of a two-user network where the users cooperatively transmit their independent information to a common destination. In the proposed FD-NCC schemes, the self-interference imposed by full-duplexing is modeled as a fading channel, whose harmful effect can be partially mitigated by interference cancellation techniques. Nevertheless, our results show that, even in the presence of self-interference, the proposed FD-NCC schemes can outperform (in terms of outage probability) the equivalent half-duplex network-coded cooperative (HD-NCC) schemes, as well as traditional cooperation techniques. Moreover, the E-outage capacity, that is, the maximum information rate achieved by the users given a target outage probability, is evaluated. Finally, we examine the use of multiple antennas at the destination node, which increases the advantage of the FD-NCC (in terms of the diversity-multiplexing trade-off and E-outage capacity).
