http://www.dsplog.com/2009/04/13/transmit-beamforming/ Webb12 apr. 2024 · The issue is phase calibration – and it’s a really big deal in beamforming systems. Calibration Between our two receive channels, there are all kinds of phase (and gain!) mismatches. For example, the SMA cables that attach the antennas to the filters are not EXACTLY the same length.
