摘要： The present invention includes a system and method by which a network of directional, wireless nodes that are not fixed in space can be optimized by optimizing each node individually. The network does not have a central control node, so each node is responsible for optimizing its surrounding topology. This is accomplished by synthesizing incoming information from neighboring nodes and determining which nodes will provide the best connections based on specific utilities each node is attempting to optimize. Neighboring nodes then exchange messages to request, accept, or reject directional connections between them based on their preferred optimizations. The overall directional network topology is achieved by consensus driven by local preferences.

摘要： Systems and methods for interference cancellation for high spectral efficiency satellite communications enabling efficient utilization of available bandwidth through overlapping adjacent channels. Data information is received along with noise information, and a filter bank is adapted to receive and filter the waveform and output channel information including a combination of data signals and adjacent channel interference signals. The filter bank is further adapted to provide estimated data signals and to calculate estimated interference signals. One or more interference generating processors are adapted to receive the calculated estimated interference signals to enable the interference generating processor to generate interference signals corresponding to the calculated estimated interference signals. The interference generating processor subtracts the interference signals from the estimated data signals in order to output relatively more accurate estimated data signals. A decision device is provided for use with the interference generating processors for estimating data signals in accordance with the relative ability of the interference processor to cancel interference with the estimated interference signals.

A further variation includes selecting an optimal number L of sub-bursts based upon system performance, and desired detection performance at a minimum operating signal to noise ratio.
