Abstract

The performance of LDPC coded four-mode multiplexed Orbital Angular Momentum (OAM) data link using QPSK signal with net data rate of 320Gbit/s is experimentally investigated. The experiment results show that crosstalk effect can be efficiently mitigated and the LDPC codes with soft decoding can provide >7 dB coding depending on OAM crosstalk.
