- W2761343874 abstract "In an interference network, joint power and admission control aims to support a maximum number of links at their specified signal to interference plus noise ratio (SINR) targets while using a minimum total transmission power. In our previous work, we formulated the joint control problem as a sparse l0-minimization problem and relaxed it to a l1-minimization problem. In this work, we propose to approximate the l0-optimization problem by a p norm minimization problem where 0 <; p <; 1, since intuitively p norm will approximate 0 norm better than 1 norm. We first show that the lp-minimization problem is strongly NP-hard and then derive a reformulation of it such that the well developed interior-point algorithms can be applied to solve it. The solution to the lp-minimization problem can efficiently guide the link's removals (deflation). Numerical simulations show the proposed heuristic outperforms the existing algorithms." @default.
