Abstract
A photonic integrated wireless sensing and communication (ISAC) system with photonic frequency multiplication and frequency conversion of orthogonal frequency division multiplexing (OFDM) signals is proposed and demonstrated. We designed and simulated a 16QAM-OFDM modulation photonic ISAC system, which is operated at 90 GHz with a bandwidth of 12.5 GHz. High-speed communication with a bit rate of 50 Gbit/s and high-resolution sensing with a range resolution of 1.2 cm is achieved. In addition, the OFDM ISAC system has the characteristics of a low sampling rate and high accuracy due to the use of optical frequency conversion.
