DFE and BCJR Performance With SD FEC in 112 GBd PAM4 IMDD Systems (W2A.23)
Presenter: Nebojsa Stojanovic, Huawei Technologies Co Ltd
Soft information quality of different DSP schemes followed by hybrid soft/hard decision FEC is investigated. We demonstrate in simulations and experiments that BCJR achieves a significant gain over DFE by providing better soft information.
