The dynamic range of a signal is a critical parameter in many practical applications. Especially in communication engineering high dynamic range mostly is considered as an important problem for technical reasons. l(infinity)-norm minimization, or in other words an anti-sparse penalty, naturally spreads the signal evenly. The advantage of spreading is the optimally reduced dynamic range of transformed signals which is a pleasant feature for many application, e.g. peak to average power ratio (PAPR) reduction for orthogonal frequency-division multiplexing (OFDM) systems. In this study, some of the main proximal splitting algorithms are deployed for l(infinity)-norm minimization. The stochastic model of anti-sparsity is investigated with the empirical results of proximal methods and already existing l(infinity)-norm minimization methods. A flexible prior is proposed to model anti-sparsity and it is used for more realistic PAPR performance analysis. |
