1. A method for evaluating link performance over a multitude of frequencies for Signal-to-Noise Ratio (SNR) optimization and mitigating interference, comprising:
communicating, from a first communication device, a first signal over a given channel in a given frequency band;
receiving, by the first communication device, (i) a Signal-to-Total Power Ratio (STPR) estimate determined based on a second signal including the first signal combined with at least one of noise and one or more interference signals, the STPR estimate accounts for at least one of (a) receiver performance including chip rate processing gain and (b) performance of an interference cancellation circuit used to remove the interference signals from the second signal, and (ii) spectral measurements based on the second signal; and
determining, by the first communication device, a predicted energy-per-bit to noise-power-spectral-density ratio (Eb/N0) condition for a plurality of frequencies within the given frequency band using the STPR estimate and the spectral measurements.
