In this work, full frequency reuse based transmission scheme is proposed for the ground-air communication systems. In full frequency reuse based systems, the receivers are interference-limited, and in this work, interference forwarding with a half-duplex (HD) dynamic decode-and-forward (DDF) relay is proposed to mitigate the interference. The HD DDF relay forwards the interference towards the interference-limited air station. The interference forwarding enhances the interference level such that the interference-limited air station can mitigate the strong interference. The diversity-multiplexing tradeoff (DMT) for the proposed HD DDF relay-aided interference mitigation scheme is evaluated. The impact of the multiplexing gain of the interfering signal on the reliability of the signal detection at the interference-limited air station is evaluated. The DMT of the proposed protocol is compared with that of the direct transmission scheme and the half-duplex decode-and-forward relay-aided interference mitigation scheme.
