The OFDM-based mm-RoF technique emerges the possibility of cost-effective and high data rate ubiquitous wireless networks. However, due to the existence of the nonlinear effects, the performance of OFDM-based mm-RoF meets the limitations. In this paper we analyses the improved performance of a 16QAM-OFDM mm-RoF with predistortion design.
This paper introduces in detail a novel 40-GHz radio over fiber (RoF) system based on optical frequency multiplication with up to 1.4Gbps 16QAM-OFDM wireless signal employing a Mach-Zehnder modulator with no optical filtering. And also what is discovered as expected during the experiment — the optimal driving power of the intensity modulator (IM) to relieve high peak-to-average power ratio (PAPR)...
This Letter proposes a low-cost Optical Frequency Multiplication (OFM) scheme based on dual drive Mach-Zehnder Modulator (DD-MZM) to generate 40-GHz millimeter-Wave (mmW) signals and 32Gbps 64QAM-OFDM signal at the center frequency of 35GHz occupying 5.6GHz bandwidth applied to Radio-over-Fiber (RoF) system. The optimal driving power of Intensity Modulator (IM) is also discovered to achieve the smallest...
