“…Consequently, in this paper, a strict phase synchronized laser is not required as a local oscillator in the RRU to demodulate the coherent optical carrier signal. Compared with the receiving unit of the traditional coherent RoF system [27,[32][33][34], the cost of the receiver and the difficulty of periodic maintenance are greatly reduced due to the absence of the local oscillator, especially in the distribution of multiple remote unit networks.…”

In this paper, we propose a radio over fiber transmission system with simultaneous wireless multi-mode operation based on multi-wavelength optical comb and pulse shaping. This study is an initial attempt to accomplish simultaneous wireless multi-mode operation on a single optical carrier. A multi-wavelength optical comb with 13 flat optical wavelengths and space of 10 GHz is achieved by utilizing radio frequency (RF)-optics modulation and parameter configuration. The central station contains four adjacent optical wavelengths separated from the multi-wavelength optical comb by a wavelength division multiplexer, that one is modulated by 4QAM-OFDM signals with an up-converted carrier frequency of 5 GHz. The signals modulated with a single-sideband can be obtained by employing pulse shaping. The single-sideband optical signals are combined with the other three optical wavelengths and then transmitted over a standard single-mode fiber with a length of 50 km. In this arrangement, we can obtain several wireless carriers with frequencies of 5 GHz, 25 GHz, 45 GHz, and 65 GHz by direct detection. These wireless carriers are used for wireless transmission between the RF remote units and the mobile terminals. Additionally, in the radio frequency (RF) remote unit, we have three pure optical sources that can be utilized for the uplink transmission. With single channel and direct optoelectronic modulation, the optical and wireless communication with 10 Gbps can be accomplished in the whole process of system network transmission.

“…In this arrangement, it doesn't need a laser with strict frequency-phase synchronization used as a local oscillator in the RRU to demodulate optical signals. Compared with the receiving unit of the coherent microwave photonics communication system [31], [33], due to the absence of the local oscillator, the cost of receiver and the difficulty of periodic maintenance are greatly reduced, especially in the case of multi-remote unit network distribution. Compared with the conventional radio over fiber (RoF) system [34]- [38], duo to the double vector modulation on a single optical carrier, the optical spectrum utilization efficiency is double.…”

A wireless communication system with tunable multicarrier based on optical comb is investigated in this paper. This study is an initial attempt to modulate multiple vector microwave signals with different frequency on a single optical carrier, and then transmit these optical signals over a standard singlemode fiber with the length of 30 km, and finally demodulate them at the remote unit via a photoelectric direct detector without strict frequency-phase synchronization. Such a design can decrease the equipment cost and improve the frequency efficiency. In the transmitting terminal unit (TTU), a flat multi-wavelength optical comb with 13 channels and the channel space of 10 GHz can be obtained by the microwave photonics technology. In the radio-frequency remote unit (RRU), we can not only obtain the wireless carriers with the frequency of 5 GHz, 10 GHz, 35 GHz, 40 GHz, 65 GHz, 70 GHz, 95 GHz, and 100 GHz via a photoelectric direct detector that are used for wireless transmission between the mobile terminal and the radio-frequency remote unit, but also get three optical sources that can be utilized for the uplink. Meanwhile, the wireless access rate can reach up to 20 Gbps between RRU and MT. In this arrangement, compared with a conventional microwave photonics link, the optical spectrum utilization efficiency and transmission rate not only can be doubled, but also the maintenance cost of RRU can be reduced greatly.
