Systems and methods for evaluating link performance over a multitude of frequencies for Signal-to-Noise Ratio (SNR) optimization and mitigating interference. The methods comprise: communicating, from a first communication device, a first signal over a given channel in a given frequency band; receiving, by the first communication device, spectral power measurements and 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 the receiver performance including chip rate processing gain and/or the performance of an interference cancellation circuit used to remove the interference signals from the second signal); and determining, by the first communication device, a predicted Signal-to-Noise Ratio (SNR) condition for a plurality of frequencies within the given frequency band using the STPR estimate and the spectral power measurements.

Systems and methods for decentralized link performance

Determining maximum transmit power by a local node. A method includes identifying one-hop neighbor nodes of the local node in the mesh network. One or more threshold maximum changes in interference caused by the local node increasing its transmit power for each of the one-hop neighbor nodes of the local node are identified. A plurality of power change values are identified. Each power change value in the plurality of power change values corresponds to a power change at the local node that would cause one of the threshold maximum changes in interference to occur at a corresponding one-hop neighbor node of the local node. A lowest power change value from among the plurality of power change values is identified. As a result, power transmitted by the local node is increased, while limiting an increase in power transmitted by the local node to no more than the lowest power change value.
