In this paper, a joint evaluation of I/Q imbalance and reconfigurable bandpass filter nonlinearity in wireless transmitters is described. An experimental analysis of complete Orthogonal Frequency Division Multiplex (OFDM) transmitter is presented for the purpose of quantifying these nonlinearities using LTE R9 3 MHz 16 QAM and LTE R9 3 MHz 64 QAM signals.
