| Summary: | We propose a mode demultiplexing method based on multichannel blind deconvolution (MBD) for a mode-division multiplexing (MDM) system. A 6 <inline-formula> <tex-math notation="LaTeX">$\times$</tex-math></inline-formula> 6 MDM transmission system is simulated to verify the performance of MBD. Compared with the frequently used least-mean-squares-based time-domain equalization (TDE) and frequency-domain equalization (FDE), MBD shows almost the same demultiplexing performance in the case of quadrature phase-shift keying (QPSK) modulation format and a better performance in the case of 16 quadrature amplitude modulation (16 QAM). Furthermore, it is also demonstrated that the proposed MBD can recover the carrier phase during the process of demultiplexing and has a fast convergence speed. |
