Themethodisa fully-digitized process at the samplingclockrate, so that it can be convenientlyimplementedby FPGAorDSP, whosesynchronizationprecision can reach 1% of the sampling interval.
For example you might have Texas Instrument or TI which is the biggest supplier in the base-band market orDSP (Digital Signal Processing) but still have competition from the likes of Lucent, Motorola, Qualcomm.
