  3. Abstract:
  4. This study investigates the Causal Cognitive Interference Channel (CC-IFC) with unlimited look-ahead, in which the cognitive user non-causally knows its entire received sequence. A coding scheme is proposed which combines the Compress-and-Forward (CF) strategy and Marton coding at the cognitive user. Using this scheme, a new inner bound on the capacity region (achievable rate region) is established for the CC-IFC with unlimited look-ahead. Further, the derived achievable rate region is extended to the Gaussian case and is compared with the previously obtained results via numerical examples, which are based on the Decode-and-Forward (DF) strategy
