Abstract
This paper analyzes the capacity of a three-user interference channel with a cognitive transmitter which non-causally knows the messages of the other two transmitters. Especially, We derive the capacity region when all interference channel gains are strong and show that the capacity is achieved by superposition coding. From the capacity results for the specific channel conditions, we also analyze the capacity region for three-user Gaussian interference channel with a cognitive transmitter.
