This paper investigates the effect of nonlinear crosstalk on the overall performance of the MIMO transmitter. It proposes a linearization technique to correct for the effect of crosstalk and hence enhance the BER performance of the MIMO system. Recently it was shown that in the presence of nonlinear crosstalk, the conventional digital predistortion technique is unable to linearize the transmitter,...
A new mode-multiplexing linear amplification with nonlinear components (MM-LINC) technique is proposed in this brief. This technique, which is referred to as reverse MM-LINC, consists of using linear amplification with nonlinear components (LINC) hardware, along with two signal decomposition modes, depending on the power of the input signal. This decomposition guarantees acceptable linearity of the...
