Low-Cost Integration of MIMO-RoF based on 5G UFMC Waveform and Wired OFDM Signal over PON

A low cost fibre-wireless (FiWi) convergent network architecture including two multiple-input multiple-output (MIMO) wireless signals based on a 5G universal filter multicarrier (UFMC) waveform and wired signal over orthogonal frequency division multiplexed passive optical network (OFDM-PON) is presented. The proposed scheme utilizes a single side band frequency translation (SSB-FT) technique to provide a smooth and cost-efficient convergent system. A proof-of-concept downstream link over a 20 km standard-PON is conducted by simulation to confirm the successful transmission of 1 Gb/s data rate for each MIMO and 2.5 Gb/s for the wired signal using error vector magnitude (EVM) and bit error rate (BER) measurements.
