METHOD AND SYSTEM OF ENHANCING SIGNAL PROCESSING IN A SHARED MEDIUM NETWORK

Granted: September 18, 2014
Application Number: 20140269758
A method implemented in a device is disclosed for networking through signals transmitted across a shared medium network. The method starts with monitoring for a first signal on a shared medium of the shared medium network. The first signal is processed after it is received and while the first signal is being processed, a set of one or more signals is received on the shared medium. Then a set of one or more amplitude increases is determined, where each amplitude increase is from an…

METHOD AND APPARATUS FOR MULTI-CARRIER MODULATION (MCM) PACKET DETECTION BASED ON PHASE DIFFERENCES

Granted: September 18, 2014
Application Number: 20140269948
A method is disclosed for detecting packet at a receiving system in a Multi-Carrier Modulation (MCM) system. The method starts with receiving a signal at the receiving system. Then a deviation value of the signal is computed, where the deviation value is computed at least partially based on phase differences between some number of carriers in the preamble. The deviation value is compared with a threshold to determine whether a packet has been detected from the received signal. In…

METHOD AND APPARATUS FOR PHASE-BASED MULTI-CARRIER MODULATION (MCM) PACKET DETECTION

Granted: September 18, 2014
Application Number: 20140269949
A method is disclosed for detecting packet at a receiving system in a Multi-Carrier Modulation (MCM) system. The method starts with receiving a signal at the receiving system. Then during the plurality of symbol durations, a set of phases of the signal for each symbol duration is obtained, where each phase is a phase of a carrier of the number of carriers. Then a set of phase variances for each carrier of the number of carriers is obtained, where each phase variance is a difference of…

DETECTING AND LOCATING POWER OUTAGES VIA LOW VOLTAGE GRID MAPPING

Granted: September 18, 2014
Application Number: 20140278162
In a power grid capable of electrical power delivery and power line communications, a distribution transformer and at least one smart meter is connected to the power grid. In one embodiment, the distribution transformer is configured to map the smart meters on the power grid to a virtual grid based upon measurements of signal metrics received from the various smart meters on the power grid, and the virtual grid is used to determine if a failure has occurred on the physical grid. A…
