  • Publication number: 20190296791
    Abstract: An electronic communication device comprises echo cancellation circuitry and signal modification circuitry. The echo cancellation circuitry may be operable to generate a first signal that approximates interference present in a second signal. The signal modification circuitry may be operable to generate a first cancellation signal in a frequency band that is not used on a communication medium over which the electronic communication device is configured to communicate. The signal modification circuitry may be operable to combine the first cancellation signal with the first signal, wherein the combining of the signals results in a modified first signal that has a lower crest factor and/or peak-to-average power ratio than the first signal. The signal modification circuitry may be operable to combine the modified first signal with the second signal to reduce interference present in the second signal.

  • Publication number: 20180287659
    Abstract: Systems and methods are provided for full duplex DOCSIS cable modem echo cancellation with training. During reception of downstream signals, echo effects on downstream signals may be determined, with at least some of the echo effects corresponding to concurrently transmitted upstream signals. Echo cancellation corrections may be determined based on the determined echo effects, and the echo cancellation corrections may be applied during processing of the downstream signals. The echo cancellation corrections may include one or both of ACI (adjacent channel interference) cancellation corrections and ALI (adjacent leakage interference) cancellation correction. The echo cancellation may include or be based on preforming echo cancellation training, during active communication and based on one or both of the downstream signals and the upstream signals.

  • Publication number: 20170187400
    Abstract: Systems and methods are provided for utilizing remote spectrum analysis of transmit bands in communication systems. A transmit band spectrum corresponding to a transmit band used in transmitting signals may be captured. The captured transmit band spectrum may be processed, and based on such processing presence of noise, distortion, interference, etc. in the transmit band spectrum may be detected, wherein the noise, distortion, interference, etc. may be introduced by one or more other systems sharing a medium used in the transmitting of the signals. One or more characteristic associated with each instance of detected noise, distortion, interference, etc. may be determined. Reporting information, related to the detection of noise, distortion, interference, etc. and/or to the determined one or more characteristics associated with each instance of detected noise, distortion, interference, etc., may be determined, and the reported information may be sent to at least one remote system.

  • Patent number: 8131229
    Abstract: Apparatus and methods for adjustment of spectral signal characteristics in polar modulators are described. A composite signal detection circuit is configured to detect when a signal trajectory of a composite signal provided to the polar modulator passes near the origin of a complex plane associated with the composite signal, and then adjusts the composite signal to pass through the origin. A spectral adjustment circuit is described to adjust AM and FM or PM components of the composite signal to reduce the deviation of an FM component of the composite signal.

  • Patent number: 7983666
    Abstract: A cancellation system that delays the received signals and cancels less than all the received signals from the delayed version of the received signals and a demodulator and despreader unit produces a demodulated and de-spreader and remodulator unit produces a remodulated and respread signal from the demodulated and despread signal with a combiner that produces a combined signal from the delayed version of the received signals and the remodulated and respread signal to identify a low power signal.

  • Patent number: 7885314
    Abstract: A cancellation system that delays received Global Positioning System (“GPS”) signals and cancels less than all of the received GPS signals from the delayed version of the received GPS signals. A delay circuit produces a delayed version of the received GPS signals and a demodulator and despreader unit produces a demodulated and despread GPS signal corresponding to one of the received GPS signals. A respreader and remodulator unit produces a remodulated and respread GPS signal from the demodulated and despread GPS signal and a combiner produces a combined GPS signal from the delayed version of the received GPS signals and the remodulated and respread GPS signal. The cancellation system and method may also store the received GPS signals and cancel less than all the received GPS signals from the stored version of the received GPS signals.

  • Patent number: 6693953
    Abstract: The present invention provides methods and apparatus for controlling power utilization in a wireless communication receiver. A representative system comprises a signal properties evaluation module, an analog to digital converter (ADC), and an analog to digital converter control module. The signal properties evaluation module evaluates the stability of a received signal, and provides an indication of the stability. The ADC control module responds to the signal properties evaluation module to select the precision of the ADC based upon the indication of the stability. The ADC has at least two modes of operation, comprising a first precision and a second precision, and is responsive to the signal properties evaluation module to operate in at least one of two modes based upon the stability. The ADC responds to the signal properties evaluation module so as to limit the amount of power consumed by the wireless communications device.

  • Patent number: 6114888
    Abstract: The current disclosure is directed toward part or all digital phase lock loop circuits, particularly those containing divide by N circuits between the voltage controlled oscillator and the phase detector. These divide by N circuits many times contain long logic count down chains. In power sensitive applications the amount of power dissipated by these divide by N circuits may be significant. The current disclosure is directed to apparatus and methods of cycling these divide by N circuits between enabled and disabled to conserve power. The changing of the enabled/disabled frequency and the duty cycle of the disabling of the divider is contemplated, as are the various ancillary factors that might be considered in determining this frequency and duty cycle. Stabilization of the loop is considered as is the changing of gain of the phase lock loop in order to improve operation as the dividers are enabled and disabled.
