Abstract: In this paper, we propose an algorithm for the classification of digital amplitude-phase modulated signals in flat fading channels with non-Gaussian noise. The additive noise is modeled by a ...

The formula for this is: ROI = (Sales growth- Marketing Cost) / Marketing Cost. There are also more elaborate ways to measure ROI, such as with campaign attributable ROI, which factors in existing ...

The approach used here is a computationally modest implementation of a maximum likelihood (ML) technique. The ML technique for estimating the complex amplitudes, chirping rates, and frequencies ...
