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 virtually performing delta-sigma digitization is provided. The method is performed on a series of digital samples output from a communication stack of a communication network. The method includes steps of obtaining a delta-sigma digitization sampling frequency for the output series of digital samples, calculating an oversampling ratio for the output series of digital samples, interpolating the output series of digital samples at a rate equivalent to the oversampling ratio, and quantizing the interpolated series of digital samples to plurality of discrete predetermined levels.

Abstract: Correction of errors within over-the-air signaling is contemplated. The error correction may include correcting over-the-air signaling used to facilitate transmitting content, broadcast television, etc. according to error correction data transmitted separately from the over-the-air signaling. A receiver may be configured to process the over-the-air signaling according to the error correction data so as to facilitate the contemplated error correction.

Abstract: A method for detecting aggressive signal transmission signatures in a wireless communication network is provided. The network includes at least one cooperative device, an access point, and at least one non-cooperative device. The method includes steps of generating a matrix of at least 8 bits configured to register each instance of at least one of a clear-to-send frame and a request-to-send frame transmitted between the at least one cooperative device and the access point during a specified duration, calculating a cumulative distribution function based on the registered instances within the generated matrix for a probability of the presence of an aggressive transmission signal by the at least one non-cooperative device within a measurable vicinity of one or more of the cooperative device and the access point, and determining the presence of the aggressive transmission signal based on the calculated cumulative distribution function being greater than a predetermined threshold.

Abstract: Facilitating echo cancellation within communication networks is contemplated, such as but not necessarily limited to facilitating echo cancellation within full-duplex (FDX) communication networks. The echo cancellation may optionally be performed with an echo canceller included as part of or otherwise associated with an FDX node used to facilitate interfacing signaling between a digital domain and an analog domain of a FDX or other communication network.
