Digital Predistortion Technique for Massive MIMO Cross Interference
This paper proposes a digital predistortion (DPD) technique capable of combating with the distortions arising due to the mixed effect of crosstalk and power amplifier (PA) nonlinearity for Massive MIMO. The proposed method is built by taking into account the complexity issue because the complexity of the model increases with the increase in the number of paths. For proof of concept, the method is implemented for 2X2 MIMO. With the simulation results, it has been established that complexity of the proposed method is much reduced for 4X4, 8X8 and 16X16 MIMO scenarios than the established multi-input digital predistortion solutions.
