摘要: We consider one-sided interference channel with two independent source-destination pairs, and a cognitive relay only link to the destination that observes interference. first assume non-causally obtains signal messages (message cognitive) whereas sources do not cooperate, provide general achievable rate region for Gaussian case. further analyze more realistic set-up where instead of source messages, knows transmitted signals both is unaware codebooks. investigate under this assumption obtain converse, thereby capacity strong relay-interference conditions. Our results suggest while relaying usually utilized as an effective technique boosting received quality, in presence interference, equally important task manage
