Background Orthogonal frequency division multiplexing has been regarded as one of the promising technologies for the optical access systems application. However, high peak-to-average power ratio will cause the signal distortion and enable the used amplifier to operate in nonlinear section. Methods In this paper, a modified selected mapping technique is introduced for reducing the peak-to-average...
A novel 60-GHz radio over fiber (RoF) system is proposed and experimentally demonstrated with 16QAM-OFDM downlink signals generated by three kinds of partial transmit sequence (PTS) segmentation methods. The 5-Gb/s 16QAM-OFDM signals are transmitted over 42 km SMF-28 and a 0.4-m wireless channel. The experimental results demonstrate that all of the PTS segmentation methods here can effectively reduce...
