Query: 5G Wireless and Wired Convergence in a Passive Optical Network using
  UF-OFDM and GFDM   The provision of both wireless and wired services in the optical access
domain will be an important function for future passive optical networks (PON).
With the emergence of 5th generation (5G) mobile communications, a move toward
a dense deployment of small cell antenna sites, in conjunction with a cloud
radio access network (C-RAN) architecture, is foreseen. This type of network
architecture greatly increases the requirement for high capacity mobile
fronthaul and backhaul links. An efficient way of achieving such connectivity
is to make use of wavelength division multiplexed (WDM) PON infrastructure
where wireless and wired services may be converged for distribution. In this
work, for the first time, the convergence of 5G wireless candidate waveforms
with a single-carrier wired signal is demonstrated in a PON. Three bands of
universally filtered orthogonal frequency division multiplexing (UF-OFDM) and
generalized frequency division multiplexing (GFDM), are transmitted at an
intermediate frequency in conjunction with a digital 10Gb/s pulse amplitude
modulation (PAM) signal in the downlink direction. Orthogonal frequency
division multiplexing (OFDM) is also evaluated as a benchmark. Results show,
for each waveform, how performance varies due to the 5G channel spacing -
indicating UF-OFDM's superiority in terms of PON convergence. Successful
transmission over 25km of fibre is also demonstrated for all waveforms.
