An Improved Cross Talk Cancelling Digital Predistortion for MIMO Transmitters

Figure 4

Simulation results of cross talk cancellation ability contour in a 2-output MIMO, where the cross talk delay of 0.4 ns is compensated by the ICTC-DPD. It shows that the ICTC-DPD can achieve higher cross talk cancellation ability than CTC-DPD when the same phase error and magnitude error of coupling coefficient estimation exist.
