Defect detector for holographic storage systems

Abstract

A system including a reconstruction module and a correlation module. The reconstruction module is configured to reconstruct data bits detected from first signals, and to generate second signals based on the reconstruction of the data bits detected from the first signals. The correlation module is configured to generate first correlation values by correlating (i) the first signals and (ii) the second signals, and to generate second correlation values by self-correlating the second signals. In response to one or more of (i) the first signals and (ii) the second signals including a floating number having (i) a plurality of bits and (ii) a sign bit, the correlation module is configured to generate one or more of (i) the first correlation values and (ii) the second correlation values based on (i) a plurality of most significant bits of the floating number and (ii) the sign bit of the floating number.
