摘要： A spectrum sensor detects the presence of incumbent signals in the television-band. The spectrum sensor can detect digital Advanced Television Systems Committee (ATSC) signals below a −114 dBm signal level and wireless microphone signals below a −110 dBm signal level with false detection rates less than 10%. A radio module receives radio-frequency signals and produces an intermediate-frequency signal reflecting signal received in a selected television channel. A baseband processor module receives the intermediate-frequency signal, digitizes it, and processes the digital data to detecting whether an incumbent signal is present in the selected channel. The processing may include using pilot detection based on power spectrum thresholding or statistic characteristic extraction to detect ATSC signals. The processing may also include using power spectrum thresholding or covariance based signal detection to detect wireless microphone signals.

摘要： Methods and apparatus for conserving power in terminal units (100) that transmit and receive modulated data over a communication loop (120) that is shared with voiceband telephone equipment are disclosed. The methods include monitoring the loop to detect a shut-down condition and reducing power consumption of certain of the electronic circuits in the terminal unit (100) upon detection of a shut-down condition. The methods also include monitoring the loop with a monitoring circuit (115) to detect a resume signal outside the voiceband frequency range on the loop (120) and restoring power to the electronic circuits when the resume signal is detected.; The apparatuses include a modulated data transmitting and receiving unit having a connector for coupling the unit to a communications loop (120), circuitry (112, 113) to transmit and receive a modulated data signal in a frequency range above voiceband, and circuitry (115) to detect a resume signal in the frequency range above voiceband and then to initiate a power up sequence for the transmit and receive circuitry (112, 113).

摘要： A residual carrier frequency offset of a signal received by a receiver, which has a local frequency oscillator that generates a carrier frequency different from a carrier frequency generated by a local frequency oscillator at a transmitter that transmitted the received signal is estimated using first and second channel impulse responses derived from first and second portions of the received signal, an estimated phase difference between the first and second channel impulse responses, and an estimate of the residual carrier frequency offset computed using the estimated phase differences. The residual carrier frequency offset is estimated after most of the carrier frequency offset has been removed from the received signal using conventional means.

摘要： Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

摘要： A technique for maintaining a predefined transmission quality in a wireless Metropolitan Area Network (MAN). Each of a plurality of Local Area Networks are coupled to a corresponding router. Each router is coupled to one or more transceivers for interconnecting the routers via wireless links. Each router stores a table representative of the topology of the MAN and receives detected indicia representative of the quality of the wireless links and representative of network traffic loads. The router adapts the manner of transmission and the path of transmission according to the indicia. As a result, the MAN is highly efficient, in terms of cost, power and bandwidth utilisation. For example, a strength of a signal received over a wireless communication link is periodically monitored for maintaining the strength within a predefined range by adjusting the transmission power.; In addition, an error rate for the data received over the link is monitored. If the received signal strength remains below the predefined range despite the transmit power having been adjusted to a maximum allowable level, and if the error rate approaches a predefined limit, one or more techniques are selectively employed to reduce the error rate while maintaining a sufficiently high network throughput. The adaptive techniques include changing the data rate, modulation level, error correction coding, and spectrum spreading. In addition, a path for the data is preferably selected according to an Open-Shortest-Path-First algorithm, though one or more alternate paths can be selected for transmitting at least a portion of the data.
