Abstract
The present invention provides a method for designing operation schedules of a fast Fourier transform (FFT) and a multiple input multiple output orthogonal frequency division multiplexing modem (MIMO-OFDM modem) thereof. According to the present invention, an operation speed of an FFT operator is set up, a receiving symbol is arranged in an OFDM symbol duration in an FFT after receiving the symbol, a transmitting symbol is arranged in an OFDM symbol duration in the FFT schedule before transmitting the symbol, a transmitting/receiving symbol which has the same timing is inserted into an idle symbol duration of the FFT schedule, an FFT schedule which is good to be deleted is deleted, and symbols of the deleted FFT schedule are re-arranged in order to not have an error occur in transmitting/receiving timing.
