Abstract: Architecture for processing a record of burst information in a transmission link. A waveform sampler samples a received waveform containing a record of symbols imposed on a carrier signal. Symbol phase of the record symbols is determined utilizing one or more metrics. Any residual carrier error is corrected, and the carrier signal is removed. The phase and time-of-arrival of the burst information associated with a maximum positive correlation value are then determined.

Abstract: Methods, systems, and devices are described for determining a preferred routing path for communicating source data from a data source to a data terminal over a network having multiple routing path options. Embodiments include receiving a source dataset at a network node; determining multiple routing path options for routing the source dataset, each comprising a set of communication links that communicatively couple the data source with the data terminal; determining a hierarchical encoding scheme for encoding the source dataset to generate a transmission; generating routing path profiles for each routing path option by evaluating each routing path option against a routing metric; determining a preferred routing path for routing the transmission by comparing the routing path profiles; and routing the transmission over the preferred routing path according to the hierarchical encoding scheme.

Abstract: Methods, systems, and devices are described for using adaptive coding and modulation (“ACM”) to adaptively communicate with a plurality of data terminals having different capabilities. Embodiments provide hierarchical communications of content, generated by applying hierarchical pre-coding schemes to the source data and then associating the pre-coding levels with coding and modulation schemes of varying order. The pre-coding and/or coding and modulation may be based on one or more capabilities of the data terminals in the network. In some embodiments, data terminals may be used to cache certain data intended for other data terminals, for example, to allow time-shifted playback of the content on terminals with varying capabilities.

Abstract: Methods, systems, and devices are described for providing predictive adaptive communications. Embodiments include a network access unit, in communication with multiple data terminals, and adapted to determine geospatial and other network data (e.g., current capability and position information relating to a designated one of the data terminals, map data, etc.), and to generate a link condition prediction as a function of the network data. The network access unit may then adaptively encode source data (e.g., using adaptive coding and modulation of hierarchically pre-coded data) to preempt impacts of changing link conditions on communications with the designated data terminal as a function of the link condition prediction.

Abstract: Methods, systems, and devices are described for communicating data from multiple data terminals to an aggregator terminal over a communication link having changing link conditions. In some embodiments, source data is received at multiple data terminals, each in communication with an aggregator terminal over a communication link. For example, during a live newscast, one mobile camera may receive live video of an event from a first position while another mobile camera receives live video of the event from a second position. For various reasons (e.g., as the cameras move) each communication link may experience independently changing link conditions. Each data terminal encodes the source data (or store source data for later encoding) as a function of its respective link conditions, and transmits encoded source data over its respective communication link to the aggregator terminal.

Abstract: Methods, systems, and devices are described for hierarchical communication of a set of source data over a communication link. Sets of representation data may be generated by applying precoding schemes to a set of source data. The sets of representation data may be associated with coding and modulation schemes of varying order. Based on certain link conditions, the sets of representation data may be adaptively coded and modulated, using their associated coding and modulation schemes, for transmission over a communication link.
