Clearly, total IMD3 is maximized when only two signals are present, and minimized when the energy is most evenly distributed. The real-world operating points between these extremes is a function of the characteristics of the individual environments. For a CR to assess the impact of the IMD, it must be able to assess the noise impact of an environment in a straightforward manner. Adaptation mechanisms are dependent on the radio's ability to predict the effect of energy on front-end perfor...
