A partially activated conjugate beamforming (PACB) is proposed for massive multiple-input multiple-output communications. where the line-of-sight (LoS) channel is dominant. Unlike the conventional conjugate beamforming which activates all the antenna elements to radiate the signals. our PACB activates only a fraction of the antennas by exploiting the spatial structure of LoS channel. https://www.spidertattooz.com/NYX-Total-Control-Drop-Foundation-Brush-PROB22-p11165/
