In this paper we consider massive multiple input multiple output (MIMO) schemes where each transmitter branch has very low resolution digital to analog converters (DACs). We present an analytical method for obtaining the statistical characterization of the transmitted signals that allows a simple and accurate performance evaluation even when there is imperfect channel state information (CSI). It is shown that, although the performance penalty associated to the use of low resolution DACs can be considerable, it can be mitigated by employing more antennas at the transmitter than at the receiver.
