“…The operation of HPAs in wireless systems may introduce serious memory effects and nonlinear distortions [12], [23], [24], causing intersymbol interference and adjacent channel interference that degrade the system's achievable bit error rate (BER) performance. The problem becomes particularly acute for high bandwidth-efficiency quadrature amplitude modulation (QAM) systems [25].…”

“…illustrates the TWTA modeling in stages 1 and 2. Since TWTA's nonlinear distortion can be considered a Wiener structure in wideband systems [2], TWTA consists of MND preceded by memory effects in Fig. 1.…”

“…For this, only the input signal with small amplitude x small (n) is selected as depicted in Fig. 1(a) since the input signal with small amplitude usually operates in the linear region of TWTA [2], [4]. For the operation in the linear region, Fig.…”
