Figure 4From: Power amplifier linearization technique with IQ imbalance and crosstalk compensation for broadband MIMO-OFDM transmittersThe proposed MIMO-PD structure. (a) 2×2 MIMO-PD implementation, (b) one branch of the MIMO-PD composed by 2(M1,1 + M1,2) memoryless polynomials, and (c) memoryless polynomial implementation of two branches (conjugate and non-conjugate).Back to article page
