  • Apparatus and methods for compensating for signal imbalance in a receiver
    Patent number: 8537925
    Abstract: Apparatus, methods and systems for compensating for an I/Q imbalance may include compensating for an imbalance between a first component of a data signal and a second component of the data signal. The data signal may be modulated by a carrier signal having a frequency error. The first component may be characterized by at least one parameter. The method may include receiving the data and carrier signals; selecting a value for the parameter such that the frequency domain energy at negative frequencies is reduced; and modifying at least one of the components based on the value.
    Type: Grant
    Filed: October 4, 2011
    Date of Patent: September 17, 2013
    Assignee: Broadcom Corporation
    Inventors: Zak Levi, Eliyahu Shusterman
