Abstract
Methods and apparatus are disclosed for ameliorating signal reception. An example method disclosed herein includes receiving a composite satellite signal comprising a desired signal component and an interference signal component, converting the received composite satellite signal to a digital received composite signal, receiving a first group of samples from the digital received composite signal, generating an interference estimate of the interference signal component based on the first group of samples, combining the interference estimate and a second sample belonging to a second group of samples to remove, partially or entirely, the interference signal component from the composite satellite signal, the first group of samples received prior to the sample belonging to the second group of samples, wherein the removal is generally independent of the code chip rate of the desired signal component and substantially retains the undistorted chip edge characteristics of the desired signal component.
