摘要：
Minimum mean-square error (MMSE) and blind equalization schemes were employed to improve bit-error rate (BER) and to mitigate intersymbol interference (ISI) generated during storage and retrieval processes of data pages in a holographic data storage system. The methods for designing and applying MMSE and blind equalization were described. A least mean square (LMS) algorithm was performed with spatial light modulator (SLM) input and charge-coupled-device (CCD) output data of the first page. The results show that the BER performance improved significantly compared with those before equalization.
