“…More than 50 km of fiber transmission underneath 7 rate Forward Error Correction (FEC) limit is accomplished. The DFB was remotely infused to get a low linewidth coherent comb source to overcome phase noise because of optical decorrelation [1]. The portrayed framework is amazingly steady to changes in fiber length.…”

This paper introduces the Quadrature Amplitude Modulation (QAM) Radio over Fiber (RoF) framework dependent on Optical Frequency Comb (OFC) generation utilizing Fabry-Perot Laser Diode (FPLD) and Continuous Wave Laser Diode (CWLD). In this, optical Millimeter-Wave (MMW) can be created ether utilizing ease FPLD with an outside optical infusion or a continuous wave laser diode. At the base, optical MMW can be recognized by utilizing photodetector in the two transmissions. The experimental results are explained by using the constellation and eye diagram.

“…Such a highly coherent low linewidth OFC renders a higher tolerance to the time delay induced between the two tones after fibre propagation thereby resulting in negligible phase noise on the resultant mmWave signal [12]. These factors result in a stable, cost efficient and highly effective system for 5G mmWave fronthaul.…”

Abstract-A 5G millimeter-wave radio over fibre optical fronthaul system based on optical heterodyning, utilising an externally injected gain switched distributed feedback laser, is successfully demonstrated. Five bands of UF-OFDM are transmitted over 25 km of fibre and a 28 GHz Vivaldi Antenna wireless link. Transmission performance below the 7% FEC limit is achieved with an aggregate total data rate of 4.56 Gb/s.

“…Since OFDM provide highly spectral efficient system and robust to the linear optical impairments such as chromatic dispersion(CD), it is still an attractive candidate for 5G research [9].The study of OFDM system also provides the basis for advanced multicarrier system such as FBMC (filter bank multicarrier) systems [10]. OFDM modulation is a simple and well studied method of multicarrier system which has also been studied in 60 GHz radio over fiber systems with various design aspects [11][12][13].…”

In this paper, we propose a new technique for synchronization and channel estimation in M-QAM OFDM radio over fiber (RoF) system by using constant amplitude zero autocorrelation (CAZAC) sequence based training preamble. Delay and correlate method is used to identify the training sequence in the received signal vector and to correct the symbol timing offset. For an optimum demodulation of OFDM signal, optimum down sampling offset position has to be identified before applying symbol timing algorithm. To solve this issue, we present the iterative method of finding optimum down sampling offset position. We show that the training preamble used for synchronization can also be applied to estimate the channel response using averaging technique. Moreover, we used the least square estimation based channel estimation method using pilot subcarriers and compare the results with training preamble based estimation.
