Outage capacity regions of multicarrier DF relaying in underwater acoustic channels
Suhail Ibrahim Al-Dharrab, Murat Uysal · 2012
In this paper, we investigate the information theoretical limits on the performance of cooperative multicarrier underwater acoustic (UWA) communication systems. We assume decode-and-forward (DF) relaying and consider non-orthogonal half-duplex cooperation. Under the assumptions of sparse and frequency-selective Rician fading channel and correlated Gaussian ambient noise, we derive the maximum achievable sum-rate and common/individual outage capacity regions for the cooperation protocol under consideration. We further investigate the effect of several parameters such as underwater temperature, carrier frequency, etc. on the outage capacity regions.
