“…At the receiver side, we can simply use an envelope detector (ED) to replace the function of a coherent detector, which usually includes expensive high-speed mixers and MMW local oscillators (LOs). An easy-to-implement intensity modulation direct detection (IM/DD) scheme can not only reduce the system cost, but also avoid the frequency-drift issue caused by the linewidth of lasers [23][24][25][26] . It is worth noting that high-order modulation formats have long been used to increase system capacity.…”

We experimentally built a W-band photonics-aided millimeter-wave radio-over-fiber transmission system and demonstrated the delivery of up to 8192-ary quadrature amplitude modulation (QAM) signal. Discrete multitone signals are converted into 1-bit data streams through delta-sigma modulation and then modulated onto a 76.2 GHz carrier. An envelope detector is used at the receiver side for direct detection. The results prove that our proposed system can support 2048QAM and 8192QAM transmission while meeting the hard decision forward error correction threshold of 3.8 × 10 −3 and the soft decision forward error correction threshold of 4.2 × 10 −2 , respectively. We believe this cost-effective scheme is a promising candidate for future high-order QAM millimeter-wave downlink transmission.
