  • Receiver with adaptive equalizer
    Patent number: 8406284
    Abstract: Receivers and methods for receiving a signal may result in improved performance by resolving specific impairments at particular levels. For example, bit error ratio (BER) in the downstream signal of an HFC network may be improved by resolving up to 6% AM hum. Thus, the receivers and methods described herein may function with dramatically improved error rates and continuous FEC lock, in relation to conventional receivers, in the presence of SCTE 40 impairments and full channel loading over the receivers entire input dynamic range.
    Type: Grant
    Filed: August 21, 2007
    Date of Patent: March 26, 2013
    Assignee: General Instrument Corporation
    Inventors: David C. Miller, Marc J. Ryba
