“…Theory in (9) shows that a receiver based on ED is completely robust against the laser phase noise effects. In [14], it is experimentally shown that, using an ED, the laser phase noise effects on the quality of the received signal can be neglected. It is needed to mention that the PMLLD laser used here and in [14] are the same.…”

“…PMLLD has been demonstrated for low-cost generation of MMW signals in the RoF communication systems [11], [12] and [13]. In the presented RoF system, an envelope detector (ED) is used for down-converting the MMW signal to intermediate frequency (IF) so that the phase noise impact on EVM results can be eliminated [14]. Using this technique, the impacts of amplitude noise on EVM results can be analyzed in a way that is free from the phase or frequency fluctuations.…”

“…Using this technique, the impacts of amplitude noise on EVM results can be analyzed in a way that is free from the phase or frequency fluctuations. In [14], the impact of phase noise on different electrical down-conversion methods in RoF system based on PMLLD has been studied. The propagation effects in RoF system based on PMLLD are also presented in [15] and [16].…”

In this paper, a complete theoretical and experimental study of amplitude noise impact on performance of radio-overfiber (RoF) communication system in millimeter-wave (MMW) frequency band is presented. A simulation method is also presented, using which one can determine the origin of the amplitude noise which has the most impact on error vector magnitude (EVM). This method is based on analyzing the trends of EVM versus received optical power. The impact of different optical and electrical noise such as relative intensity noise, shot noise and thermal noise on EVM is precisely studied employing experimental and theoretical analysis. In the proposed RoF system, two techniques are used to generate MMW signal, and the EVM results are compared from amplitude noise viewpoint. In the first technique, two independent distributed feedback lasers are used to generate MMW signal at the output of a photodetector, and the second technique is based on a passively mode-locked laser diode. Impact of optical sources phase noise on performance of the system is removed using a noncoherent down-conversion method based on envelope detector. Using this method, a very good matching between the experimental and the simulation results is observed.Index Terms-Distributed feedback (DFB) laser, envelope detector, error vector magnitude (EVM), millimeter wave (MMW), passively mode-locked laser diode (PMLLD), phase noise, radioover-fiber (RoF), relative intensity noise (RIN), shot noise.

“…RoF technology also allows centralizing broadband optical signal processing functions such as optical frequency up-conversion, with the objective of limiting the use of expensive broadband RF transmitters in BSs [2]. Different solutions have been proposed for 60 GHz mmW generation and transmission [3]- [10]. As in [3], a mode-locked laser is employed to generate 60 GHz mmW by beating of two optical modes with 60 GHz frequency offset.…”

We propose a 60-GHz orthogonal frequency division multiplexing (OFDM) radio over fiber system based on direct modulation-direct detection using an externally injected gainswitched DFB laser with adaptive modulation format. Power fading due to chromatic dispersion is mitigated by optimizing the bias current. Adaptive modulation for OFDM is used to improve the signal transmission performance. A 15.31-Gb/s 60-GHz OFDM signal generation and transmission over 25-km standard single-mode fiber is experimentally demonstrated.Index Terms-Radio over fiber, orthogonal frequency division multiplexing, power fading, adaptive modulation.
