Abstract:
An apparatus for synchronizing a signal received over a first receive channel in a radio receiver, the radio receiver having multiple receive channels and a demodulator, the apparatus comprising:first means for receiving a first signal corresponding to the first receive channel; second means for receiving a second signal corresponding to a second receive channel; and synchronizing means, responsive to said first means and said second means, for synchronizing the first signal operative as a function of the first signal and the second signal, wherein said synchronizing means includes: a control unit for generating a sampling phase for use in synchronizing the first signal; a decimator, connected to said first means and said control unit, for decimating the first signal responsive to the sampling phase generated by said control unit; and a metric computer responsive to said decimator, for generating a metric predictive of the performance of the demodulator.
