In this paper, we investigate the capacity of known interference channel, where the receiver knows the interference data but not the channel gain of the interference data, assuming the use of Gaussian modulations. We first present a tight upper bound for the capacity of this known-interference channel. After that, we obtain the achievable rate of the channel with a blind known interference cancellation...
In this paper, we aim to obtain the optimal joint power and rate control that maximizes the interference-aware secondary system utility subject to the interference temperature constraints of primary users (PUs) on the basis of the information-theoretic interference processing technique. In particular, we first draw the capacity-approaching rate region of secondary users (SUs) with given transmit power...
This paper investigates interference-cancellation schemes at the receiver, in which the interference data, which is valid data intended for another receiver, is known a priori. The interference channel, however, is unknown (the blind part). Such a priori knowledge is common in wireless relay networks. For example, a relay could be relaying data that was previously transmitted by a node A. If node...
