20100309805 | TESTING UPSTREAM CABLE CHANNELS - In order to measure the performance of a DOCSIS upstream channel as well as to locate impairments, a special test signal is transmitted in a time slot of the upstream channel by a test instrument positioned anywhere within the CATV plant. A second test instrument, located at the termination point of the upstream plant, then detects, recovers, and processes the test signal in order to complete the measurement. The typical methods used to detect and recover bursted signals within a DOCSIS upstream channel use precise timing information transmitted in a corresponding DOCSIS downstream channel. Unfortunately, the downstream channel and thus the precise timing information are not always available to the secondary test instrument. The present invention also describes an apparatus and method for detecting a bursted test signal without the use of the DOCSIS upstream channel timing. | 12-09-2010 |
20110096684 | IDENTIFYING AN ORIGIN OF A DOCSIS UPSTREAM BURST - A method and an apparatus for identifying an origin of captured DOCSIS upstream bursts are disclosed. Upstream bursts are captured without knowing their allocated time slots in advance. Information from an upstream channel descriptor is used to generate RF waveforms of upstream burst preambles, which arc then correlated to the captured upstream waveforms to determine the type of captured upstream bursts without having to decode the latter. Once the type of the captured upstream bursts is determined, information from the upstream channel descriptor is further used to demodulate and decode the upstream burst, so that CPE MAC addresses can be extracted. From the extracted CPE MAC addresses, the origin of the captured upstream bursts can be identified. The identification of origins of captured upstream bursts assists in locating faults in the cable network. | 04-28-2011 |

20090282320 | ITERATIVE DECODER WITH STOPPING CRITERION GENERATED FROM ERROR LOCATION POLYNOMIAL - A decoder for error correction an encoded message, such as one encoded by a turbo encoder, with reduced iterations due to an improved stopping criterion. The decoder includes an error correction loop that iteratively processes a message that is encoded prior to transmittal over a communication channel.
