Patent ID: 7672655

Claim:
A phase mismatch compensation system comprising: a first feedback loop comprising a first summer, wherein said first summer has a first input that communicates with a first phase of a received signal and has an output; a second feed back loop comprising a second summer, wherein said second summer has a first input that communicates with a second phase of said received signal and has an output, wherein said second phase is offset from said first phase; a first filter that selectively filters said output of said first summer; an adaptive control module that determines a predicted shift between said first and second phases of said received signal based on an output of said first filter and an actual shift between said first and second phases of said received signal; and a correction module that communicates with an output of said adaptive control module and said first phase and second phase of said received signal, that outputs a mismatch correction to second inputs of said first and second summers respectively.
