Abstract: Techniques for determining power levels of radios, including a time domain duplexing (TDD) system, in shared frequency spectrum is provided. A TDD radio, of the TDD system, in a neighborhood having a largest interference contribution in the frequency spectrum at the point. Transmit power levels are determined for (a) the selected TDD radio, (b) other radios in the neighborhood that are not part of the TDD system, and (c) at least one radio in the TDD system that is not the TDD radio having the largest interference contribution in the frequency spectrum. Thus, interference margin may be fairly allocated to radios in neighborhood(s) about protection points.

Abstract: A computing device includes a processor and memory storing instructions that are executable to determine a median of a first mixture distribution. The instructions are also executable to determine a parent mean, a parent standard deviation, and boundaries for each of multiple segments in the first mixture distribution. The instructions are also executable to determine a segment mean and a segment second moment for each segment based on the parent mean, the parent standard deviation, and the boundaries for the respective segment. The instructions are also executable to determine a scaled probability for each segment. The instructions are also executable to determine a mixture mean and a mixture standard deviation for the first mixture distribution based on the segment mean, the segment second moment, and the scaled probability for each segment in the first mixture distribution.

Abstract: In one embodiment, a method is provided. The method comprises defining propagation analysis points for radial line Rp; obtaining, from an external database, terrain elevation data for the radial line Rp up to a maximum radial distance; determining the contour point for the radial line Rp; and upon determining the contour points for M radii, generating a protection zone perimeter.

Abstract: A method is provided. The method comprises: selecting a new protection point in a dynamic protection area; creating an initial sort list of radios; determining look angles; determining which look angle includes most radios in its main beam; determining a modified sort list and an initial move list for the determined look angle; determining a certain percentile of aggregate interference power spectral density at the new protection point for radios that are in a main beam for each of remaining look angles; sorting, by level of certain percentile of aggregate interference power spectral density, the remaining look angles; and generating a move list of radios.

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 more accurately determining interference contribution at a point in a neighborhood of a time division duplexing (TDD) system operating in shared frequency spectrum. If at least one TDD radio, of a TDD system, is in the neighborhood, then determine a largest interference level, at the point in the shared frequency spectrum, by a TDD radio of the TDD system, where the TDD radio is in the region around the point. The largest interference level is selected as the aggregate interference contribution of the TDD system for interference analysis in the shared spectrum at the point.

Abstract: The present disclosure describes systems and methods for determining intermodulation distortion in a system such as, but not limited to, a communication system. In an embodiment, intermodulation distortion is determined by injecting a signal into a frequency band which interacts with a second signal, searching a second frequency band for a product signal formed from the first and second signals, applying a cyclostationarity detection technique to the product signal and identifying the product signal as an intermodulation distortion signal.

Abstract: A method for detecting a physical cell identification (PCI) for a wireless coverage area is provided. The method includes establishing a hypothesis having a set of values including a number of subbands, a set of synchronization sequences, and a frequency offset; iteratively updating and testing the set of values against extracted baseband data until a current set of values results in frame synchronization; and decoding the physical cell identification based on the set of values that resulted in frame synchronization.
