Abstract: A method for diminishing passive intermodulation (PIM) is provided. The method comprises: upsampling an uplink baseband modulated signal; upsampling a downlink baseband modulated signal; determining a time delay for the upsampled downlink baseband modulated signal; time delaying the upsampled downlink baseband modulated signal by the determined time delay; estimating a third order PIM distortion (PIMD) product by filtering the time delayed, upsampled downlink baseband modulated signal with a third order power series kernel; generating a first filtered signal by subtracting the estimated third order PIMD product from the upsampled downlink baseband modulated signal; estimating a Nth order PIMD product by filtering the time delayed, upsampled downlink baseband modulated signal with a Nth order power series kernel; generating a nth filtered signal by subtracting the estimated Nth order PIMD product from the n−1th filtered signal; and downsampling the nth filtered signal.

Abstract: Techniques for modelling a radio network in a geographic region utilizing shared spectra are disclosed. Population data is obtained for the geographic region. A number of radios per channel in the geographic region, N′, is determined. Candidate geographic location for radios in the geographic region are determined. For every channel in the shared spectra, at least one of a static dataset and a dynamic dataset is determined. At least one set of output data, that is a statistical characterization of the radio network, is generated using at least one of the static dataset and the dynamic dataset, to aid in design of the radio network.

Abstract: Techniques are provided for enhancing accuracy of modelling aggregate interference at each protection point of a geographical area in a region having an urban or suburban morphology type whilst reducing processing requirements by diminishing a number of elevation data that must be obtained from external sources. The geographical area may be a priority access license protection area, a grandfathered wireless protection zone, or other geographic area which must be protected from interference.

Abstract: Techniques are provided for more efficiently determining frequency spectrum to allocate to General Authorized Access (GAA) citizens broadband radio service device(s) (CBSD(s)). Efficiency is enhanced by reducing a number of sets of frequency spectrum(s) by reducing a number of colors (assigned to nodes of connected set(s) of the network graph(s)) to which assignable frequency spectrum changes amongst the set(s).

Abstract: A system and method for determining transmission delay in a communications system. In some embodiments, satellite positioning information having System Frame Number (SFN) information may be received for a mobile device and observed time difference of arrival (OTDOA) measurements may be received for a mobile device. A location of the mobile device may be determined as a function of the received satellite positioning information. A Global Positioning System (GPS) time estimate may be determined as a function of the determined location of the mobile device. Transmission delay between a node serving the mobile device and an antenna serving the mobile device may be determined as a function of the received OTDOA measurements and determined GPS time estimate.
