Abstract

We consider the ℓ ∞ -norm minimization problem, which has been investigated in various practical applications. Based on an equivalent problem reformulation we propose an efficient algorithm that is suitable for implementation on parallel hardware architectures. Simulation results show that when applied to the peak-to-average ratio reduction problem, the algorithm achieves the solution obtained by the primal-dual hybrid gradient approach with proximal operator while significantly reducing the required running time for convergence.
