Abstract
The present invention relates to an orthogonal frequency-division multiplexing receiver, and more particular to an orthogonal frequency-division multiplexing receiver including an FFT/IFFT operating core and a scheduler. In order to simultaneously share the FFT/IFFT operating core, the scheduler manages input/output timings of FFT/IFFT operations and control signals. The FFT/IFFT operating core supports decimation-in-time (DIT) and decimation-in-frequency (DIF) FFT/IFFT operations at the same time.
