AB  - In this Letter, we first propose and demonstrate a real-time in-band full duplex 
      (IBFD) transmission system based on adaptive optical self-interference 
      cancellation (OSIC). The field programmable gate array (FPGA) is used for 
      high-speed and real-time orthogonal frequency-division multiplexing (OFDM) 
      transmission. The hybrid criteria regular triangle (RT) algorithm is first 
      proposed to combine signal power and the bit error rate (BER) together as the 
      objective function to realize the adaptive control process. With this algorithm, 
      the real-time adaptive OSIC system is able to converge and fully recover the 
      signal of interest (SOI) within 12 sampling times, which is by far the fastest, 
      to the best of our knowledge, convergence under the real-time transmission 
      scenario. Experiments show that the system can achieve 28 dB cancellation depth 
      across 0-1.45 GHz wideband, and 40 dB cancellation depth at 900 MHz, 2.4 GHz, and 
      5 GHz, which is the best cancellation performance in current real-time adaptive 
      OSIC schemes and shows the potential of our system in different commercial 
      applications.
