Digital predistortion (DPD) is a major linearization technique for nonlinear power amplifier (PA). While DPD requires the measurement of PA instantaneous behavior for calculating PA inverse characteristic. In designing system-level DPD, it is necessary to develop a correlation algorithm for measuring the instantaneous behaviour of remote PAs when the local PA testbed is lacked. This paper proposes a novel correlation algorithm to measure the instantaneous behavior of PAs. In this proposed algorithm, the influence of PA nonlinearity and memory effects on PN sequence is modeled and compensated, and this is followed by the conventional compensation of the carrier offset. In the real measurement of a solid state PA (SSPA).
