Abstract

In this paper we propose to use a so-called 'Slave' power amplifier (PA) to remove the distortions caused by the non-linear "Master" high power amplifier (HPA) in multicarrier systems. We derive the mutual information (MI) expressions for the proposed scheme and perform simulations to obtain the spectral mask. It is shown that by adding an additional "Slave" PA we increase the MI and improve the spectral mask, while maintaining the same supplied power as in regular multicarrier system with a single "Master" HPA.
