SpletBeamforming by Precoding : This is the technique that change the beam pattern (radiation form) by applying a specific precoding matrix. This is the technique used in LTE. In LTE, following transmission mode is implemeting 'BeamForming' implictely or explicitely. TM 6 - Closed loop spatial multiplexing using a single transmission layer. SpletInverting the precoding is accomplished by matrix pseudoinversion of the precoding matrices. It returns a cell array, cws , of soft bit vectors, and a cell array, symbols , of received constellation symbol vectors resulting from performing the inverse of Physical Downlink Shared Channel (PDSCH) processing.
