Third, I would like to show the experimental verification of the compensation for IQI, nonlinear PA response and MIMO Linear self-interference. Step 3 of the proposed method was performed using the channel response parameters for the main and auxiliary transmission paths. The main path contained a 16-QAM signal with an IQ imbalance that was corrected for the IQ imbalance and pre-compensated for a nonlinear PA response. The auxiliary path contained the 16-QAM signal with a different training code.
