  • Patent number: 9461683
    Abstract: A method and apparatus is disclosed to determine communications receiver parameters from multiple channels of a received communications signal and to configure and/or adjust communications receiver parameters to acquire one or more channels from among the multiple channels of the received communications signal. A communications receiver observes a multi-channel communication signal as it passes through a communication channel. The communications receiver determines one or more communications receiver parameters from the multiple channels of the received communications signal. The communications receiver configures and/or adjusts communications receiver parameters to acquire the one or more channels from among the multiple channels of the received communications signal.

  • Patent number: 8638889
    Abstract: A method and apparatus are described that result in an improved acquisition of a received communication signal containing a large frequency offset. The method and apparatus raises a derotated sequence of data to a power of an integer provide a sinusoidal spectral component. The method and apparatus determines a cross product based upon the sinusoidal spectral component to provide a phase error. The method and apparatus determines an oscillator signal based upon the phase error. The method and apparatus adjusts the received communication signal based upon the oscillator signal to compensate for the large frequency offset to provide the derotated sequence of data.

  • Patent number: 8564462
    Abstract: A method and apparatus is disclosed to compensate for impairments within a data converter such that its output is a more accurate representation of its input. The data converter includes a main data converter, a reference data converter, and a correction module. The main data converter may be characterized as having the impairments. As a result, the output of the main data converter is not the most accurate representation of its input. The reference data converter is designed such that the impairments are not present. The correction module estimates the impairments present within the main data converter using its output and the reference data converter to generate corrections coefficients. The correction module adjusts the output of the main data converter using the corrections coefficients to improve the performance of the data converter.

  • Patent number: 8437387
    Abstract: An apparatus is disclosed to compensate for non-linear effects resulting from the transmitter, the receiver, and/or the communication channel in a communication system. A receiver of the communication system contains an image cancellation module that compensates for images generated during the modulation and/or demodulation process. The image cancellation module includes a fine carrier correction loop to correct for frequency offsets between the transmitter and receiver. The image cancellation module includes a coarse acquisition mode and a decision directed mode. The decision directed mode allows for a larger signal-to-noise ratio for the receiver when compared against the coarse acquisition mode.
