  Abstract

This paper considers a one-way decode-and-forward relay network consisting of a source, a relay, and a destination. The achievable rate is determined by the transmit power values from the source and relay, and the first and second transmit time durations. Based on the channel gain, this paper proposes the joint transmit power and time allocation scheme for increasing the achievable rate under the sum transmit power constraint and sum transmit time duration constraint. This work presents closed-form expressions for the transmit power and time duration. Numerical results show that the achievable rate of the proposed power and time allocation scheme is greater than those of the other schemes, such as the equal power and optimal time allocation scheme, optimal power and equal time allocation scheme, and equal power and equal time allocation scheme.
