Patent attributes
A receiver for combining multipath significant components and correcting the frequency error and the phase error associated with each significant component consists of delay devices, path strength estimators, error signal generators, scaling signal updating devices, a decision circuit, and a controller. The controller extracts information about each significant component and generates initial scaling signals and other timing and control signals. Different significant components delayed by different amount of time through corresponding delay devices and multiplied by corresponding scaling signals from scaling signal updating devices, are added together for the decision circuit to make a decision. The scaling signal updating devices update the scaling signal according to the path strength signals generated by the path strength estimators through monitoring significant components and the error signals generated by the error signal generators through comparing the signals sending to the decision circuit and the decision made by the decision circuit.
