Figure 7From: Theoretical analysis and compensation for the joint effects of HPA nonlinearity and RF crosstalk in VBLAST MIMO-OFDM systems over Rayleigh fading channelTheoretical and simulation results for BER vs SNR for MIMO-OFDM systems. Polynomial approximation of HPA with 16-QAM, Nc = 64, Nt = Nr = 2, and IBO = {4-8-10} dB.Back to article page
