METHOD AND DEVICE FOR REDUCTION OF CORRELATED INTERFERENCE IN MULTICHANNEL RECEIVER SYSTEMS CORRELATED WITH DIGITAL BEAM FORMING

摘要

The invention relates to a method for reducing correlated present in the receiving channels of a multi-channel receiver system noise, wherein- The receiving channels of the multi-channel receiver system each comprise a receiving unit, a receiver and an analog / digital converter, and- The multi-channel receiver system for performing a digital beamforming based on the received in the individual receiving channels and digitized signals is set, and- The multi-channel receiver system after application of the digital beamforming has a defined directional characteristic with a main receiving direction greatest sensitivity, whereina targeted preforming of the directional characteristic of the multi-channel receiver system (1) is made in another receiving area, which does not correspond to the aforementioned main receiving direction of the multi-channel receiver system (1), by introducing defined phase shifts in the individual receiving channels between the receiving unit (61) and receiver (40), wherein the phase shifts are selected such that when undoing the preforming in the subsequent digital beamforming the correlated interference signals (30) of the individual receiving channels in the main receiving direction are superposed destructively. A corresponding device is also content of the patent application.
