Software radio signals with several channels have high dynamic range, making them very prone to nonlinear distortion effects, namely those inherent to an efficient power amplification. In this paper we present analytical approach evaluation for evaluating the impact of nonlinear devices in software radio signals. As an application, we will consider the nonlinear amplification of software radio signals where we have a high number of channels with substantially different powers.
