Abstract: 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.

Abstract: Selecting a control channel set in a communication system involves monitoring received signals to identify a plurality of nodes of interest (NOI) and determining Eb/N0 values for a plurality of control channels. For this purpose, a data metric and spectral data can be provided to the communication device by the respective NOI for which Eb/N0 values are being determined. A comparison is made of the Eb/N0 values for all NOI to select an optimal control channel set. The optimal control channel set is then used by the communication device to transmit the control channel information to the plurality of NOI.

Abstract: Providing signal-to-noise ratio information to a local transmitter node. A method includes receiving data in a signal transmitted on a data channel from the local transmitter node. A first signal-to-total-power ratio for the signal assuming no jamming of the signal is occurring is computed. A second signal-to-total-power ratio for the signal with factors included assuming jamming is occurring is computed. The first signal-to-total-power ratio to the second signal-to-total-power ratio are compared to determine if they differ by a predetermined amount. The method includes determining that the predetermined amount is exceeded, and as a result, a jammed signal-to-noise ratio is computed assuming jamming is occurring. The jammed signal-to-noise ratio is sent to the local transmitter node to allow the local transmitter to respond to the jammed signal-to-noise ratio.

Abstract: Joining subnets in mobile ad-hoc network (MANET) environment. A method includes, based on SNR, power and data rate information between a first gateway node for a first subnet and a second gateway node for a second subnet, determining a rate at which the first and the second subnets can connect if nodes in the first subnet reduce signal transmit rate to a predetermined level. The method further includes as a result of determining that the determined rate meets or exceeds a predetermined threshold, then joining the first and second subnets by joining the first and second subnets via the first and second gateway nodes and causing nodes in the first subnet to reduce signal transmit rate to the predetermined level.

Abstract: A communications system may include mobile communications nodes operating according to a current topology and reconfigurable to a new topology. Each mobile communications node may include a wireless transceiver, and a controller configured to transmit spectral performance data to adjacent nodes and receive spectral performance data from the adjacent nodes. The controller may identify potential topologies for the adjacent nodes based on the spectral performance data, select a subset of potential topologies from among the potential topologies, generate a respective performance score for each potential topology of the subset of potential topologies, and switch to a new topology from among the subset of potential topologies based upon the performance scores.

Abstract: A transmitter in a frequency domain duplexing (FDD) network system is configured to receive spectral information from neighbor receiver nodes. For each of the neighbor receiver nodes, the transmitter computes an SNR at each of the plurality of frequencies, forming an SNR curve. For each of the transmit frequencies, the transmitter identifies minimum SNR values among the SNR values on the SNR curves. The minimum SNR values form a composite minimum curve. Based on the composite minimum curve, the transmitter determines whether an SNR of a current transmit frequency is above (1) a first threshold associated with an operating SNR, or (2) a second threshold associated with a maximum of the composite minimum curve. Based on the determination, the transmitter determines whether a new transmit frequency is selected to replace the current transmit frequency.
