Abstract
In this paper, we develop novel Automatic Repeat reQuest (ARQ) key sharing protocols for correlated fading channels. In particular, a novel role of “dumb antennas” in overcoming the negative impact of spatial correlation, on the achievable secrecy rates, is unveiled. We further develop an adaptive rate allocation policy which achieves higher secrecy rates by exploiting the channel temporal correlation. The performance gains offered by the proposed schemes are demonstrated by a comprehensive set of numerical results.
