Figure 6From: Power amplifier linearization technique with IQ imbalance and crosstalk compensation for broadband MIMO-OFDM transmittersAM/AM and AM/PM curves at the output of the PA without linearization, with conventional predistorters and with our MIMO-PD with a SNR = 40 dB. Crosstalk ρ = -20 dB, IQ imbalances of β1 = 5% and ϑ 1 = 5°, β2 = 3% and ϑ2 = 3°, and DC offset, |ε1| = 0.1 and |ε2| = 0.07 for (a) PA-1, (b) PA-2.Back to article page
