Patent number: 10070437Abstract: Methods for using a detector to monitor and detect channel occupancy are disclosed. The detector resides on a station within a network using a framed format having a periodic time structure. When non-cooperative transmissions are detected by the network, the detector assesses the availability of a backup channel enabling migration of the network. The backup channel serves to allow the network to migrate transparently when the current channel becomes unavailable. The backup channel, however, could be occupied by another network that results in the migrating network interfering with the network already using the backup channel. Thus, the detector detects active transmission sources on the backup channel to determine whether the backup channel is occupied. Methods for using the detector include scheduling detection intervals asynchronously. The asynchronous detection uses offsets from a reference point within a frame.Type: GrantFiled: October 19, 2016Date of Patent: September 4, 2018Assignee: Shared Spectrum CompanyInventors: Mark Allen McHenry, Dmitry Dain, Eugene Livis, Karl Steadman, Olga Ritterbush

Patent number: 9854461Abstract: A method for classifying a signal can be used by a station or stations within a network to classify the signal as non-cooperative (NC) or a target signal. The method performs classification over channels within a frequency spectrum. The percentage of power above a first threshold is computed for a channel. Based on the percentage, a signal is classified as a narrowband signal. If the percentage indicates the absence of a narrowband signal, then a lower second threshold is applied to confirm the absence according to the percentage of power above the second threshold. The signal is classified as a narrowband signal or pre-classified as a wideband signal based on the percentage. Pre-classified wideband signals are classified as a wideband NC signal or target signal using spectrum masks.Type: GrantFiled: July 9, 2014Date of Patent: December 26, 2017Assignee: Shared Spectrum CompanyInventors: Eugene Livis, Mark Allen McHenry, Dmitry Dain, Karl Steadman, Olga Ritterbush
