“…Compared with previous studies [5][6][7][8][9][10][11], the proposed scheme has such merits. First, in a hybrid ONU (HONU), alternative access is realized only with a PC, polarization stabilizer, and polarization beam splitter (PBS) instead of the optical filters or interleaves (ILs) usually used in conventional schemes.…”

“…In [10], a tunable laser is used to provide a coherent optical local oscillator (LO) for homo-/heterodyne beating to coherently down-convert the optical signal to the baseband electrical one for wired access or to the mm-wave one for wireless access according to the requirement of the user terminals. The authors of [11] proposed a novel coherent access network architecture that integrates ROF with ultradense-WDM-PON (UDWDM-PON) to simultaneously provide both multi-gigabit wired and wireless services.…”

“…It is well known fact that direct detection techniques fail miserably to counter turbulence-induced signal fading which in turn leads to erroneous detection, see [1]- [3]. Taking a cue from the success of coherent designs in electronic and RF communication receivers, fiber optical links have also made major headway in reaping benefits from this detection scheme, see [16], [30], [39]- [41]. Moreover recent advances in the field of photonic device design have simplified the inclusion of otherwise complex coherent reception into optical link designs.…”

“…A lesser complex and cost‐efficient way is to use digital signal processing (DSP) techniques to compensate for these fibre impairments in the electrical domain. Recently, various research works have been reported by different research groups to enhance the system performance of optical modulation formats [3–15]. Mehra et al .…”
