The method includes acquiring a signal (501); inputting (502), at a first time, a received symbol to a demodulator having a plurality of outputs to produce a set of early outputs; inputting (504), at a second time, the received symbol to the demodulator to produce a set of on-time outputs; inputting (505), at a third time, the received symbol to the demodulator to produce a set of late outputs; and comparing (506) at least one output in the set of early outputs with at least one output in the set of late outputs to produce a timing measure.

[ We claim:] [1.] A method for receiving a signal in a digital radio frequency communication system, the signal comprising a plurality of received symbols associated with a plurality of transmitted symbols, the method comprising the steps of:inputting, at a first time, a received symbol of the plurality of received symbols associated with a transmitted symbol of the plurality of transmitted symbols to a demodulator having a plurality of outputs to produce a set of early outputs;inputting, at a second time, the received symbol to the demodulator to produce a set of on-time outputs;inputting, at a third time, the received symbol to the demodulator to produce a set of late outputs;comparing a predetermined number of outputs in the set of early outputs with a predetermined number of outputs in the set of late outputs to produce a set of timing measures;storing the set of timing measures in a memory;inputting a predetermined number of outputs in the set of on-time outputs to an estimator, the estimator outputting an estimate of the transmitted symbol;based on the estimate of the transmitted symbol, selecting a timing measure from the set of timing measures in the memory; andbased on the selection, adjusting a time for receiving the signal.
