Abstract
We present a 100GHz millimeter-wave communication enabled by a photonics-assisted intensity modulation and direct detection system. The frequency-resolved discrete multi-tone (DMT) modulation is used to adapt the nonlinear response of the system and increase the rate of transmission compared to conventional pulse amplitude modulation. By loading different number of bits to the subcarriers based on the channel frequency response, 20 Gbps DMT signals is transmitted over 0.25 m free space distance, and the measured bit error rate (BER) is below the 7% FEC threshold without any equalization. This work is expected to provide a cost-effective solution to achieve high-speed millimeter-wave transmission for future beyond 5G and 6G mobile communications.
