Delivery of 40 Gbit/s W-band signal over 4600 m wireless distance employing advanced digital signal processing

Abstract

We experimentally built a photonics-aided long-distance large-capacity millimeter-wave wireless transmission system and demonstrated a delivery of 40 Gbit/s W-band 16-ary quadrature amplitude modulation (QAM) signal over 4600 m wireless distance at 88.5 GHz. Advanced offline digital signal processing algorithms are proposed and employed for signal recovery, which makes the bit-error ratio under 2.4 × 10 −2 . To the best of our knowledge, this is the first field-trial demonstration of >4 km W-band 16QAM signal transmission, and the result achieves a record-breaking product of wireless transmission capacity and distance, i.e., 184 (Gbit/s)•km, for high-speed and long-distance W-band wireless communication.

“…The feasibility of long-distance high-speed MMW transmission has already been demonstrated, in which different MMW generation methods and multidimensional multiplexing techniques are employed [11][12][13][14][15][16][17][18][19] . However, there is still some modification we can make on the existing MMW-RoF schemes to improve the cost-effectiveness.…”
