Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink message which may include an indication of a precoder applied to one or more downlink signals. The UE may receive the one or more downlink signals using a demodulation reference signal (DMRS) and the precoder, where the one or more downlink signals may be mismatched in gain and phase. The UE may perform an iterative channel estimation procedure to estimate the downlink channel. The UE may then perform a gain and phase mismatch equalization procedure to equalize an estimated gain and phase mismatch of the one or more downlink signals based on the estimated downlink channel and the precoder. The UE may then receive one or more equalized downlink signals in accordance with the gain and phase mismatch equalization procedure.
