提出了一种基于多信道盲解卷积（MBD）的模分复用（MDM）系统的模分复用方法。通过对一个6 × 6MDM传输系统的仿真，验证了MBD的性能.与常用的基于最小均方的时域均衡（TDE）和频域均衡（FDE）相比，MBD在正交相移键控（QPSK）调制格式下具有几乎相同的解复用性能，而在16正交幅度调制（16 QAM）下具有更好的解复用性能。此外，它也表明，建议MBD可以恢复载波相位在解复用过程中，并具有快速的收敛速度。
We propose a mode demultiplexing method based on multichannel blind deconvolution (MBD) for a mode-division multiplexing (MDM) system. A 6 χ 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.
