I think it means Inphase and Quadrature in the constellation of BPSK,or 16-QAM etc [/u]

as I understand, the question is related to the OFDM signal.
The way signal is formed by independently modulating subcarriers and then IFFT making parralel to Serial in OFDM signal. On the receive side, we first FFT the OFDM signal making serial to parrallel subcarriers and then demodulate the independent subcarriers.
So it must be FFT before IQ demodulation.
