In this paper, we offer a simple but general framework for analyzing the statistical properties of mobile-to-mobile (M2M) fading channels. Differently from other contributions that can be found in the literature, we are interested in end-to-end performance metrics rather than in simply analyzing the statistical behavior of the so-called product channel. As a consequence, our proposed framework is...
In this paper, the impact of non-Markovian distributed primary radio (PR) on/off activities on the opportunity time for secondary radio (SR) transmission is studied. The licensed spectrum is partitioned into N frequency bins (FBs) and each primary user is assumed to require only one FB for transmission. The PR activity in each FB is modeled as an independent on/off process. The sojourn time for PR...
In a bi-directional relay channel, two nodes wish to exchange independent messages over a shared wireless half-duplex channel with the help of relays. Recent work has considered information theoretic limits of the bi-directional relay channel with a single relay. In this work we consider bi-directional relaying with multiple relays. We derive achievable rate regions and outer bounds for half-duplex...
