摘要： A method, system, network and device provide Smart Grid Radio Frequency Interference (RFI) detection. One or more symbols or chips present in one or more received radio frequency signals are detected and the presence of one or more erred symbols or chips in the detected one or more symbols present in the received one or more radio frequency signals determined. A correlation in time between the one or more erred symbols or chips and an infrastructure waveform associated with electrical infrastructure can be determined. When the determined correlation indicates the electrical infrastructure as a source of detectable radio frequency interference to a device, a pattern flag is generated. The pattern flag or pattern flag representation can be stored and/or transmitted.

摘要： A low power consumption protocol for low power communication devices attached to an asynchronous network is described. In this protocol, a communication device is used as a high communication duty cycle Mediation Device (MD), thus permitting other communication devices to use a low communication duty cycle framing structure. The MD functions as a storage and retrieval service for messages between two devices when one device is not able to communicate. When the previously unavailable device becomes available, it can check in with the MD to retrieve any missed messages and respond to these messages accordingly. In a communication network, each of the low power communication devices can be configured to behave as MD's for a small amount of time. Sharing this responsibility among all communication devices in the network allows each device to maintain an low average communication duty cycle. This technique is applicable to a low power, low cost, zero-configuring, self-organizing, asynchronous network.

摘要： A peak and valley measuring circuit (40) featuring a single digital-to-analog converter (DAC) (100), a peak counter (110), a valley counter (120), and a comparator (130). The peak and valley measuring circuit (40) uses the peak counter (110) when detecting peaks of the recovered audio signal and the valley counter (120) when detecting valleys of the recovered audio signal. The DAC (100) is used in conjunction with one of the counters (110) or (120) depending on whether peaks or valleys are being detected, and is preferably a current-mode DAC.

摘要： A method (300) and cognitive radio (CR) wireless device (102) are provided for dynamically accessing spectrum in an opportunistic spectrum access wireless communication system (100). The method includes: transmitting, from a CR wireless device, a signal (216) having a first bandwidth within an unoccupied portion of spectrum (206), and after a time interval (T3) following the transmitting, and upon determining that an adjacent spectral quantum is occupied, transmitting from the CR wireless device a signal (216) having a second bandwidth, the second bandwidth being less than the first bandwidth. The method doubles a rate of growth of bandwidth of a transmitted signal when a spectral quantum adjacent to one side of the signal is unoccupied and a spectral quantum adjacent to the other side of the signal is occupied. The method utilizes knowledge of location of the CR wireless device and of band-edges to intelligently use spectral fence quanta.

摘要： A process for merging and using the Mediation Device Protocol with a network layer protocol. Under the merged protocol, each device joining a network enters into two stages: the Set-Up Stage and the Normal Operational Stage. During the Set-Up Stage, the device identifies its neighbors, builds a neighborhood list, obtains a Logical ID, and picks a parent node in the network. After the Set-Up Stage is complete, the device enters the Normal Operational Stage where it will send/receive control and data messages, invite and help new nodes to join the network, recover from broken links or topology changes, and other normal network operations.

摘要： A transceiver device (52 or 10) operates as a source of a data transmission in a communication system (50) capable of dynamically allocating spectrum for transmission of the data transmission between the transceiver device (52) and a second transceiver device (51). The transceiver device (10) includes a transmitter, a receiver coupled to the transmitter and a processor or controller (12) coupled to the transmitter and receiver. The transceiver device is programmed to monitor the spectrum (channels 1-13 of FIG. 3) to determine if a portion (channels 4-8 for example in time slot 8) of the spectrum is available. The transceiver determines what portion of the spectrum is desired for data transmission and then transmits (see time slots 11 and 13) the data transmission within a dynamically selected portion of the available spectrum.
