An adaptive decision-feedback channel estimation for coherent optical OFDM

Adaptive channel estimation methods are proposed for reduced guard-interval (RGI) CO-OFDM. Channel estimation is updated adaptively after decoding a sequence of OFDM symbols using LS or MMSE decision-feedback from demodulator to channel estimator.
