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.
The orthogonality of Mode Division Multiplexing (MDM) with Wavelength division multiplexing (WDM) and
Polarization Division Multiplexing (PDM) is investigated applying WDM and PDM transmission over the LP11 mode in
a few-moded fiber. Two wavelengths, each carrying 10Gbit/s signals in two orthogonal polarizations are successfully
transmitted with the LP11 mode in a 10km long 2-mode fiber, resulting in a total 40Gbit/s data rate for one LP mode.
This experiment demonstrates that MDM is orthogonal with WDM and PDM and can be regarded as a new additional
dimension to increase optical networks' capacity.

This paper experimentally demonstrates the feasibility of a 2 x 2 MIMO optical communication system based on mode
group diversion multiplexing in the presence of strong mode crosstalk over 250m GI-MMF. The parallel signal detection
and processing are realized through the use of PD array.

This paper introduces two schemes to generate millimeter-wave
(mm-wave) BPSK and M-ASK signals in Base Station
in Radio over Fiber (RoF) system based on cascaded Dual-Drive
Mach-Zehnder modulators (DD-MZM). A BPSKmodulated
mm-wave RoF system is proposed by controlling the amplitudes of baseband digital signal. Another scheme
to generate M-ASK-modulated mm-wave in BS is based on commanding the power of Intermediated Frequency (IF)
signal. Both schemes can make the remote local reference signal available in the BS, which makes the system costefficient.
The proposed schemes are verified by theoretical derivation and simulation.
