Fiber Wireless Transmission of 8.3-Gb/s/ch QPSK-OFDM Signals in 75–110-GHz Band

Abstract

The photonic generation of electrical orthogonal frequency-division multiplexing (OFDM) modulated wireless signals in the 75j110 GHz band is experimentally demonstrated employing in-phase/quadrature electrooptical modulation and optical heterodyn upconversion. The wireless transmission of 16-quadrature-amplitude-modulation OFDM signals is demonstrated with a bit error rate performance within the forward error correction limits. Signals of 19.1 Gb/s in 6.3-GHz bandwidth are transmitted over up to 1.3-m wireless distance. Optical comb generation is further employed to support different channels, allowing the cost and energy efficiency of the system to be increased and supporting different users in the system. Four channels at 9.6 Gb/s/ch in 14.4-GHz bandwidth are generated and transmitted over up to 1.3-m wireless distance. The transmission of a 9.6-Gb/s singlechannel signal occupying 3.2-GHz bandwidth over 22.8 km of standard single-mode fiber and 0.6 m of wireless distance is also demonstrated in the multiband system.

“…Moreover, it has become a potential candidate to solve the bit rate mismatch between the wireless and fiber communications [11]. Recently, many institutions have done research on W-band mm-wave signal generation and transmission [12][13][14][15][16][17][18][19][20][21]. In [12][13][14][15][16], two independent lasers are heterodyne mixed to obtain the W-band signal at BS.…”
