Abstract

We discuss experimental results of a versatile nonbinary modulation and channel code appropriate for two-dimensional page-oriented holographic memories. An enumerative permutation code is used to provide a modulation code that permits a simple maximum-likelihood detection scheme. Experimental results from the IBM Demon testbed are used to characterize the performance and feasibility of the proposed modulation and channel codes. A reverse coding technique is introduced to combat the effects of error propagation on the modulation-code performance. We find experimentally that level-3 pixels achieve the best practical results, offering an 11–35% improvement in capacity and a 12% increase in readout rate as compared with local binary thresholding techniques.
