Abstract: An apparatus for use in a receiver (100) of a wireless communication system is provided. The apparatus comprises a first filter (340) having a first cutoff frequency, a second filter (350) having a second cutoff frequency, a first data bit estimator (360) coupled to the first filter (340), a second data bit estimator (361) coupled to the second filter (350), a third data bit estimator (363), and decision logic (370) dynamically selecting one of the first and second filters based on a first bit count from the first data bit estimator (360), a second bit count from the second data bit estimator (361), and a third bit count from the third data bit estimator (363).
