Channel-encoded and SVD-assisted MIMO Multimode Transmission Schemes with Iterative Detection
In this contribution a coherent (2× 2) MIMO (multiple input multiple output) transmission with iterative detection over a measured multimode fiber channel at 1325 nm as well as at 1570 nm operating wavelength is studied. For the channel measurements a fibre length of 1 ,4 km were chosen. Extrinsic information transfer (EXIT) charts are used for analyzing and optimizing the convergence behaviour of the iterative demapping and decoding. Our results show that in order to achieve the best bit-error rate, not necessarily all MIMO layers have to be activated.
