In this paper, study on computational complexity is implemented in a bidirectional 60GHz radio over fiber (RoF) system with 5Gb/s 16QAM-OFDM downstream signals generated by selected mapping (SLM) technique. 5Gb/s 16QAM-OFDM signals are transmitted over one 42km SMF-28 and one 0.4m wireless channel. The computational complexity comparison of different schemes with various number of branches is accomplished...
We demonstrate that interleaved segmentation technique provides a trade-off between PAPR and computational complexity in 60GHz RoF system with 5Gb/s 16QAM-OFDM downlink. Moreover, the receiver sensitivity is effectively enhanced using this method.
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...
