An intelligent electronic device for a Substation Automation or Distribution Automation system as well as to a method and computer program product for providing it. The beam position control system includes a beam position sensing system that generates one or more satellite beams which are used to determine the position of a main beam. A second conduit section transfers the sample from the pump to a receptacle for collecting the sample. A digital processor including a computational unit is coupled to the detector and is responsive to the plurality of images so that it develops 3-D coordinate positions and related image information for the plurality of surface portions of the object. A channel response is estimated at the multiple of the chip rate. Soft-input and soft-output decoders are provided to receive the channel information in order to calculate an estimated interference value.
