Compensation of nonlinear distortion in MIMO OFDM wireless communication systems

This paper presents analysis of nonlinear distortion and crosstalk compensation in Multiple Input Multiple Output (MIMO) OFDM wireless transmitters. This paper demonstrates that nonlinear crosstalk affects the performance of digital predistorter and it cannot be compensated by the conventional Memory Polynomial digital predistortion technique. Also, it has been shown that proposed CO-DPD technique can compensate the effect of nonlinear crosstalk in 2×2 MIMO OFDM wireless transmitters.
