N2 - In this paper, a cooperative power control scheme is proposed for two-user Gaussian interference channel (GIC) to mitigate the interference and improve the sum-rate. In the proposed scheme, codewords are divided into several segments. By jointly adjusting the power of each segment for the two users, the proposed scheme achieves a balance between increasing the entropy of signal and decreasing the entropy of interference, and thus maximizes the sum-rate. To solve the sum-rate maximization problem, an iterative algorithm combining both simulated annealing and gradient descent methods is also proposed. Numerical results show that the proposed scheme not only achieves higher sum-rate, but also provides better user fairness compared with the traditional schemes.
