Abstract
In this paper, the MIMO precoder selection of LTE uplink (UL) is evaluated taking into account the gain/phase variation between SRS and PUSCH. The gain/phase variation introduced by radio impairment is modeled and the impact on precoding gain is analyzed. The simulation results show that gain variation has a stronger impact on the precoding gain than phase variation. Specifically, a gain variation of 9 dB costs 5 dB in performance.
