Method for determining the channel gain between emitters and receivers

Anders la Cour-Harbo (Inventor), Jakob Stoustrup (Inventor)

Research output: Patent

Abstract

A method for determining the channel gain between one or more emitter(s) and one or more receiver(s) by using a linear transform, such as a wavelet transform. Provides a fast and robust method for determining the channel gain, the signal being emitted with a very low power since received signals are easily resolved at the receiver. The method is employed in a three dimensional pointing device for a computer improving the possibility of moving the pointer in three dimensions. Information may be obtained about objects positioned in the signal path. May be employed for door openers or for determining the position of a remote control or for reducing “Cross talk” in electrical components.
