    Abstract: A method and decoder for decoding a hierarchically coded digital video bitstream which can process a high resolution television picture in real time and which is made, up of a number of individual decoder modules, connected in parallel, which each have less real time processing power than is necessary, but which when combined, have at least the necessary processing power needed to process the bitstream in real time. The decoder includes a system controller which detects the hierarchical code indicating bits and slices and communicates this information to a slice parser which dynamically allocates the bitstream among the digital modules as needed on a per slice basis.

    Abstract: A detector module (100) is operable in a cognitive radio device and capable of determining channel occupancy. The detector module comprises a sensor (110) for sensing incumbent signals at a variable sensing threshold, wherein the sensor generates a first occupancy indication indicating whether the channel includes an incumbent signal having a sensing metric above the variable sensing threshold; a geo-location unit (120) for generating a second occupancy indication based on a location of the detector module; and a decision unit (130) for generating an occupancy decision based on both the first occupancy indication and the second occupancy indication.

    Abstract: An apparatus and method is disclosed for providing a Quality of Service (QoS) service schedule and bandwidth allocation message to a wireless station in a wireless network. The apparatus of the invention comprises a hybrid coordinator that is capable of (1) creating a Quality of Service (QoS) service schedule and a bandwidth allocation message for a wireless station and (2) sending the QoS service schedule and the bandwidth allocation message to the wireless station. The wireless station is capable of using the scheduling information to perform power management by entering a power save mode during times when the hybrid coordinator has not scheduled any transmission opportunities.

    Abstract: The invention includes a method and device for identifying opportunities to transmit in a radio network. The method and device listen for a first, second, and third period of time to detect first, second, and third busy slots. A processor recognizes a sequence of the first, second, and third busy slots as a function of time, performs a Randomized Hough Transform on the sequence, generates a histogram based on the Randomized Hough Transform, identifies peaks in the histogram, determines whether the peaks correspond to a known radar, and identifies an opportunity to transmit.

    Abstract: Self-coexistence of first and second wireless communication networks (200) is improved by transmitting a coexistence beacon from a first station (210, 220) of the first wireless communication network (200) to a first station (210, 220) of the second wireless communication network (200. The coexistence beacon includes information about a traffic reservation of the first station (210, 220) of the first wireless communication network (200). The first station (210, 220) of the second wireless communication network (200) may then use this information in a variety of ways to reduce data collisions between the two networks (200). It can communicate this information to a base station (210) of the second wireless communication network (200). The base station (210) of the second wireless communication network (200) can then use this information to more efficiently allocate frequency channels and/or time slots for future traffic reservations of the first station (220) of the second wireless communication network (200).

    Abstract: In a wireless communication network (200) comprising a base station (210) and a plurality of remote terminals (220), the plurality of remote terminals (220) are divided into a plurality of clusters (230) for communication with the base station (210), and each of the remote terminals (220) is assigned to a cluster (230) based on at least one characteristic, measured by one or more of the remote terminals (220), of one or more external signals transmitted by one or more external terrestrial transmitters (250) not associated with the communication network (200). Accordingly: a parameter of a communication between the base station (210) and each remote terminal (220) may be selected according to the cluster (230) to which each remote terminal (220) belongs; remote terminals (220) within a cluster (230) may be enabled to communicate directly with each other; and/or remote terminals (220) may be selected to perform frequency spectrum profile measurements of the frequency band used by the communication network (200) according to the clusters (230) to which they are assigned.
