Abstract
Example embodiments of the present disclosure relate to a transmitter, method, apparatus and computer readable storage medium for quantized precoding in a massive multiple-input multiple-output (MIMO) system. In example embodiments, a transmitter determines a normalized factor for precoding of a plurality of signals intended for a plurality of receivers. The first device precodes the plurality of intended signals using the normalized factor by iteratively performing acts. The acts include determining, by using the normalized factor, a descending direction of a difference between the plurality of intended signals and corresponding signals received at the plurality of receivers, a descending rate of the difference being above a threshold rate in the descending direction, and determining a plurality of precoded signals based on the descending direction. Then, the first device quantizes the plurality of precoded signals for transmission by the transmitter to the plurality of receivers.
