Similarly to the digital domain, a signal-to-noise ratio (SNR) measure to assess the performance of theDNA-based retrieval scheme in terms of database size and source statistics is defined. With approximations, it is shown that the SNR of any finite sizeDNA-based database is upper bounded by the SNR of an infinitely large one with the same source distribution. Computer simulations are presented to validate the theoretical outcomes. date: 2007-09 type: Conference or Workshop Item type: PeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/815/1/Tsaftaris_2007.pdf identifier: Tsaftaris, Sotirios A. and Katsaggelos, Aggelos K.
