Efficient Mobile Fronthaul Using Windowed OFDM Exhibiting High CFO Tolerance and Strong OOB-leakage Suppression with Low DSP Complexity

A novel windowed-OFDM transmission scheme is demonstrated to achieve 2.2-dB improvement of carrier-frequency-offset tolerance and 20-dB out-of-band-leakage suppression for MMW-RoF mobile fronthaul, with low computational complexity and no additional overhead owing to effective time-domain windowing.
