Abstract: A resource allocation method is provided for a non-orthogonal multiple access distribution of access network users communicatively coupled to a single transport medium. The method includes steps of allocating a first frequency and time domain resource to a first user and a second frequency and time domain resource to a second user of the access network users, obtaining channel information regarding a particular communication channel of the access network for which resources are allocated, grouping the first user with the second user based on an overlap of the first frequency and time domain resource with the second frequency and time domain resource, and assigning the first user to a different power allocation resource than the second user within the frequency and time domain overlap.

Abstract: The present disclosure generally relates to apparatus, software and methods for managing multi-channel network traffic to alleviate congestion, improve service quality and make efficient use of channel capacity. The disclosed apparatus, software and methods alleviate congestion and improve service quality by minimizing variance within a channel and/or increase overall traffic flow by minimizing the variance between channels. One or both of these objectives can be accomplished using modern portfolio theory to optimize at least one network usage parameter based on the mean and variance of the parameter(s).

Abstract: A method for equalizer correction in a communication network includes (a) obtaining raw equalizer coefficients in a frequency domain, (b) removing time delay from the raw equalizer coefficients to generate corrected equalizer coefficients in a time domain such that a direct current (DC) corrected equalizer coefficient of the corrected equalizer coefficients has a phase of zero, and (c) converting the corrected equalizer coefficients from the time domain to the frequency domain.

Abstract: A communication system includes an earth station configured to receive a downlink transmission from a satellite and transmit an uplink transmission to the satellite. The communication system further includes a server in operable communication with the earth station, a beacon detector in operable communication with the server, an access point configured to operate within a proximity of the earth station, and a beacon transmitter disposed within close proximity to the access point. The beacon transmitter is configured to transmit a beacon signal to one or more of the server and the beacon detector. The beacon signal uniquely identifies the access point. The server is configured to implement a measurement-based protection scheme with respect to at least one of the downlink transmission and the uplink transmission.

Abstract: A method for dynamic allocation of communication resources includes (1) determining a risk-return characterization of a plurality of communication resource allocations across a plurality of communication channels in a communication system, (2) selecting a first allocation of the plurality of communication resource allocations from the risk-return characterization according to at least one predetermined criterium, and (3) automatically allocating communication resources among the plurality of communication channels according to the first allocation.
