  • Method and apparatus for performing digital timing recovery on oversampled 802.11b baseband signals
    Patent number: 7295601
    Abstract: An apparatus and method for performing digital timing recovery includes a rotating demultiplexor receiving a four times oversampled baseband signal and providing four downsampled phases at respective outputs. Each output is processed by a correlation detector which computes a peak sum signal for each downsampled phase. The peak sum signals are processed to produce a best phase select output signal. The best phase select output signal is used to select the optimum sampling phase. Symbol timing is then determined based on the relative peak offset in the best downsampled phase.
