  • Method and Apparatus for Controlling Power of a Transmitted Signal
    Publication number: 20070087707
    Abstract: In the method and apparatus of controlling power of a transmitted communication signal, a communication signal is amplified and transmitted. At least one parameter on the transmitted signal is received, and a measure of interference with the transmitted signal is determined based on the received parameter. An average power level of the communication signal is increased by clipping the communication signal prior to amplification by an amount based on the determined measure.
    Type: Application

  • Frequency offset compensation for communication systems
    Publication number: 20040067741
    Abstract: In communications between a pair of stations using modulated carrier signals, a first station estimates the carrier frequency offset with respect to the second station and transmits signals that are responsive to the estimated carrier frequency offset. The first station may adjust the carrier frequency of the signals it transmits in response to the estimated carrier frequency offset, and/or transmit data to the second station representing the estimated carrier frequency offset. The second station adjusts the carrier frequency of the signals it transmits to the first station, and/or compensates for carrier frequency offset in its processing of received signals, in response to estimated carrier frequency offset data received from the first station.
