  Abstract

This paper considers an amplify-and-forward one-way full-duplex relay network consisting of a source, a relay, and a destination. Because there is the self-interference (SI) channel estimation error at the relay and the dynamic range of analog-to-digital converter is limited, the SI cannot be completely canceled. Due to the residual SI, the achievable rate in the current time slot is affected by the transmit power value from the relay in the previous time slot. Based on the transmit power from the relay in the previous time slot, this paper proposes the power allocation scheme for increasing the achievable rate under the sum power constraint. This work presents closed-form expressions for the transmit power values from the source and relay in each time slot. Numerical results show that the achievable rate of the proposed power allocation scheme is greater than that of the equal power allocation scheme.
