    • Rate-constrained Relaying: A Model for Cooperation with Limited Relay Resources 

      Sabharwal, Ashutosh; Mitra, Urbashi (2005-06-01)
      In this paper, the impact of limited resources on achievable rates in relay channels is investigated. Resource limitation is modeled as a rate constraint, Rbar, which constrains the rate at which a relay can reliably <i>decode</i> or <i>source-code</i> data. With this constraint in hand, the achievable rates for several protocols are derived ...
