RF (Radio Frequency) Signal Processing refers to the manipulation and analysis of signals within the radio frequency range. This field is crucial for various applications, including wireless communications, radar systems, satellite communication, RF identification (RFID), and more. RF signal processing involves techniques and technologies to handle signals within the frequency band typically ranging from a few kilohertz (kHz) to several gigahertz (GHz).
We demonstrate, for the first time, real-time blind source separation of interfering GHz transmitters using photonic weights controlled by an RF-System-on-Chip FPGA. This analog system achieves multi-antenna signal separation with millisecond execution latency.
