Uncertainty of Reconstruction with List-Decoding from
Uniform-Tandem-Duplication Noise
Abstract
We propose a list-decoding scheme for reconstruction codes in the context of
uniform-tandem-duplication noise, which can be viewed as an application of the
associative memory model to this setting. We find the uncertainty associated
with $m>2$ strings (where a previous paper considered $m=2$) in asymptotic
terms, where code-words are taken from an error-correcting code. Thus, we find
the trade-off between the design minimum distance, the number of errors, the
acceptable list size and the resulting uncertainty, which corresponds to the
required number of distinct retrieved outputs for successful reconstruction. It
is therefore seen that by accepting list-decoding one may decrease coding
redundancy, or the required number of reads, or both.
