Figure 9From: Power amplifier linearization technique with IQ imbalance and crosstalk compensation for broadband MIMO-OFDM transmittersSpectral regrowth versus polynomial order with crosstalk between the transmitters ρ = - 20 dB (spectral mask defined for mobile Wimax is plotted). The DC offset is |ε1| = |ε2| = 0. (a) PA-1 with SNR = 40 dB, (b) PA-1 with SNR = ∞ (without measurement noise), (c) PA-2 with SNR = 40 dB, (d) PA-2 with SNR = ∞ (without measurement noise).Back to article page
