Abstract
In this article, several design and complexity issues of the optimal physical layer resource allocation problem for generic interference channels are surveyed. The computational complexity, the convexity as well as the duality of the optimal resource allocation problem is discussed. Various existing algorithms for resource allocation are presented and compared. Open research problems are discussed throughout the article.
