We propose and experimentally demonstrate a novel inter-/intra-radio-access-technology (RAT) carrier-aggregation scheme for next generation 5G heterogeneous mobile data network. The real-time standard 4G-LTE signal is carrier-aggregated with three broadband 60GHz millimeter-wave (MMW) signals based on proposed optical-domain band-mapping method. © 2015 Viajes el Corte Ingles, VECISA.

In this paper, 40GHz OFDM-RoF system with an I/Q modulator is demonstrated. The experimental results show that 18.8-Gb/s 64-QAM-OFDM signal carried by 38-GHz mm-wave after fiber-wireless link is robust to the synchronization timing errors with windowing technique. © OSA 2014. Source

Dual-polarization two-subcarrier coherent optical orthogonal frequency division multiplexing (CO-OFDM) transmission and reception is successfully demonstrated with blind equalization. A two-subcarrier quadrature phase shift keyed OFDM (QPSK-OFDM) signal can be equalized as a 9-ary quadrature amplitude modulation signal in the time domain with the cascaded multimodulus algorithm equalization method. The nonlinear effect resistance and transmission distance can be enhanced compared with the traditional CO-OFDM transmission system based on frequency equalization with training sequence. © 2014 Optical Society of America.

Quad-Carrier Quadrature Phase Shift Keyed orthogonal frequency division multiplexing (QPSK-OFDM) signal transmission and reception is successfully demonstrated with blind equalization like a 25-ary quadrature amplitude modulation (25-QAM) signal with cascaded multimodulus algorithm (CMMA) equalization. The phase recovery can be realized with simple Viterbi algorithm and the frequency offset estimation (FOE) should be done with 25-QAM signal before 4-point fast Fourier transform (FFT). 48-Gbit/s Quad-Carrier QPSK-OFDM signal is successfully transmitted over 80-km SMF-28 without penalty. © 2013 Optical Society of America.

We demonstrated four-channel WDM 256.51Gb/s 16QAM-DMT short-reach optical-amplifier-free inter-connection with real-time reception. We achieved highest capacity DMT signal transmission over 2.4-km SMF with the BER under SD-FEC limitation of 2.4×1 0-2. © 2015 Viajes el Corte Ingles, VECISA. Source
