1024-QAM Analog Waveform Transmission Over a Seamless Fiber-Wireless System in W Band

Abstract

We demonstrate a high-fidelity seamless fiber– wireless system in the W band for high-precision analog waveform transmission. The system is realized using a stable radio-over-fiber transmission and a direct receiver in the W band. Satisfactory performance was experimentally confirmed for 512- and 1024-quadrature amplitude modulation orthogonal frequency division multiplexing signals, showing that the seamless system can provide precise analog waveform transmission of radio-wave signals in future mobile networks.
