title: Equalization of two-mode fiber based MIMO signals with larger receiver sets.
abstract: In this paper, we demonstrate channel equalization for two-modefiber based MIMO system with the size of receiver larger than that of transmitter. The proposed configuration is verified via experiments of 102-Gb/s CO-OFDM mode-division multiplexed systems. We compare performances of three channel equalization algorithms including zero-forcing (ZF), minimum-mean-square-error (MMSE), and successive-interference-cancellation (SIC). Our results show that the 4 x 6 MIMO system can improve the receiver sensitivity by 1.8, 2.9, and 4.9 dB for ZF, MMSE, and SIC, respectively.
