    摘要: An integrated global navigation satellite system (GNSS) receiver may be operable to decompose GNSS IF signals associated with GPS satellites and/or GLONASS satellites into a constituent narrowband GPS data stream and/or a plurality of constituent narrowband GLONASS data streams utilizing, for example, a GPS IF tuner and/or one or more GLONASS IF tuners. The narrowband GLONASS data streams and/or the narrowband GPS data stream may be processed at reduced sampling rates utilizing a shared sample memory in the integrated GNSS receiver. The narrowband GLONASS data streams and/or the narrowband GPS data stream may be stored in allocated sections of the shared sample memory. The stored narrowband GLONASS data streams and/or the stored narrowband GPS data stream may be processed using a correlation such as a fast Fourier transform (FFT) correlation.

    摘要: A two part signal acquisition process includes a parallel signal detection process and signal verification/false alarm rejection process. A massively parallel architecture of acquisition correlators search a large region of the time-frequency uncertainty during the parallel signal detection process to identify the most likely detections for each search dwell. Concurrent with the parallel signal detection process performed by the acquisition correlators, the current list of most likely detections is examined with additional search dwells in the verification/false alarm rejection process. The verification/false alarm rejection process is performed by a plurality of independent correlators or tracking channels. Under software control, the tracking channels perform repeated dwells on the most likely detections until they can be dismissed as false alarms or verified as the desired signal.

    摘要: A communication system includes an optical network, a first POP, and a second POP. The first POP receives user communications from a first user system and transfers the user communications to the optical network over a first optical wavelength.

    摘要: A system and method are provided for delivery of broadcast data over an augmented tree network that includes a content server, a tree server, an augmentation server and at least one node. The content server streams a fraction of the broadcast data to the tree server, and streams a complement to the fraction of the broadcast data to the augmentation server. A node connects to the tree server, thereby receiving the fraction of the broadcast data, the fraction having a positive value less than one. The node connects to the augmentation server, thereby receiving the complement to the fraction of the broadcast data from the augmentation server. The node assembles the fraction of the broadcast data with the complement to the fraction of the broadcast data to reassemble the broadcast data, whereby broadcast data is delivered to the node.

    摘要: A communication system includes nodes that exchange communications over optical fibers. In the event of a fault, the nodes implement ring protection for a first set of the communications and implement mesh protection for a second set of the communications. Ring protection may be used for two degree nodes and mesh protection may be used for higher degree nodes, or a customer may select between ring protection and mesh protection.

    摘要: A global navigation satellite system (GNSS) receiver may be operable to quantize two-dimensional GNSS sample data with an in-phase (I) and quadrature (Q) pair to two-dimensional quantized data with a magnitude and angle pair using the polar quantization, for example, an unrestricted polar quantization. The GNSS receiver may be operable to reduce a size of the two-dimensional quantized data for storage by representing the two-dimensional quantized data by the one-dimensional symbol data. The one-dimensional symbol data may be stored in a random access memory (RAM) for further processing. The I and Q pair associated with the one-dimensional symbol data stored in the RAM may be retrieved and processed by the GNSS receiver using a correlation such as a fast Fourier transform (FFT) correlation.
