In this paper, we consider the achievable sum secrecy rate in full-duplex wiretap channel in the presence of an eavesdropper and imperfect channel state information (CSI). We assume that the users participating in full-duplex communication and the eavesdropper have single antenna each. The users have individual transmit power constraints. They also transmit jamming signals to improve the secrec...

A new method for capacity and spectral efficiency increases is a full-duplex communication, where sending receiving are done simultaneously. Hence, severe interference leaked from the transmitter to receiver, which can disrupt system’s operation completely. For reduction, transceiver tries estimate interfering symbols remove their effects. typical use Hammerstein model. In this method, nonlinea...
