Figure 7From: Power amplifier linearization technique with IQ imbalance and crosstalk compensation for broadband MIMO-OFDM transmittersConstellation map 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 imbalance of β1 = 5% and ϑ1 = 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
