Abstract

In this paper, we realized a digital holographic optical m emoiy system which has a bi BER(bit-error-rate) performance. To enhance the eir correcting capability, we adopted hybrid error coffection technicpe. An adapUve decision-feedback equalizer(DFE) with forward filter was introduced to mitigate ISI(intersymbol-interference) generated cbixing stcrage and reirieval of 2-dimension1 data in 1ioloaphic memy system. We showed experimental results with improved BER performance.
