Document Type and Number:
WIPO Patent Application WO2005101656
Kind Code:
B1
Abstract:
A method of controlling the operation of an equalizer (210, 216), wherein the equalizer is adapted to receive a transmitted signal (76, 78) comprising at least one predetermined sequence of symbols, includes the step of developing a set of samples from a received signal. At least one plurality of samples is identified, wherein the at least one plurality of samples corresponds to the at least one predetermined sequence of symbols. The equalizer is then operated in a selected one of three modes. A first mode is selected if the at least one plurality of samples is identified, wherein the first mode includes the step of developing a signal-to-noise ratio (SNR) (100). A second mode is selected if the at least one plurality of samples is identified and the SNR is greater than a first predetermined threshold. A third mode is selected if the at least one plurality of samples is identified and the SNR is greater than a second predetermined threshold.
