In this chapter, we present the adaptive system design for the short-range RA-UAC to improve the communication reliability. We design the adaptive RA-UAC system in three steps. As a fundamental step, we derive the optimal power allocation and distribution between the source and the relay with individual and total power constraints. In the second step, we implement channel prediction to compensate the channel variation during CSI signal feedback using the RLS adaptive filter. In the last step, the Lloyd algorithm is adopted to quantize CSI efficiently to adapt to the band-limited UWA channels.
