“…Moreover, implementing MIMO without MMF will be much more complex and expensive. In the existing transmission schemes, as studied in 31,32,33 , the optical carrier is modulated with high frequency RF signals for transportation over silica based optical fiber 16 . For example, to achieve MIMO transmission, multiple laser sources, high frequency local oscillators (LOs) and wide range bandwidth EDFAs will be required to employ such a higher order MIMO system which ultimately make the system complex and less cost efficient.…”

In this paper, a full duplex Millimeter Wave (mm-wave) enabled Radio-over-Fiber (RoF) architecture is proposed for Distributed Antenna Systems (DAS). This architecture is capable of achieving transmission of 16 × 16 optical Multiple Input Multiple Output (MIMO) spatial streams at 12 Gbps per spatial stream by employing Wavelength Division Multiplexing (WDM) and exploiting its other degrees of freedom such as polarization states and modes of wavelengths. A single laser source based multi-wavelength comb and wavelength reuse techniques along with Plastic Optical Fiber (POF) are employed to make the proposed architecture cost efficient.Optical heterodyne detection is performed at the Radio Access Unit (RAU) to generate mm-wave carrier frequency at 60 GHz. Channel equalization is achieved for Pulse Amplitute Modulation (PAM-4) data signal by employing Least Mean Square (LMS) equalizer to mitigate the optical fiber channel effects. Our proposed system supports 16 × 12 Gbps for Downlink (DL) and Uplink (UL) transmissions. To evaluate the performance of the proposed system, we compare the receiver sensitivities at FEC limit of 3.8 × 10 −3 of Bit Error Ratio (BER) of Back to Back (B2B) system, employing no fiber effects, with its counterparts. We show that acceptable power penalties for the fiber lengths of 200 meter and 400 meter are achieved for both LP01 and LP11 modes in DL and UL directions.
