In [14], and [15] the Analog/Digital (A/D) conversion is modeled as a linear stochastic process. Low resolution A/D conversion WebAnalog beamforming has hitherto been used in the mm-wave systems; however, it is suboptimal compared to digital beamforming. As analog beamforming relies entirely on RF domain processing, the performance is limited by quantization of phase angles and the support of only single stream transmissions [10,11].
