16 Oct 2004 | | Subject: | Soft Condensed Matter | cond-mat.soft | | Affiliation: | Institute of Complexity Science, Department of Automation Engineering, Qingdao University, People’s Republic of China, Centre for Biomedical Engineering (CBME) and School of Electrical & Electronic Engineering, The University of Adelaide, Adel | | Abstract: | This paper presents a thorough evaluation of a bistable system versus a matched filter in detecting bipolar pulse signals. The detectability of the bistable system can be optimized by adding noise, i.e. the stochastic resonance (SR) phenomenon. This SR effect is also demonstrated by approximate statistical detection theory of the bistable system and corresponding numerical simulations. Furthermore, the performance comparison results between the bistable system and the matched filter show that (a) the bistable system is more robust than the matched filter in detecting signals with disturbed pulse rates, and (b) the bistable system approaches the performance of the matched filter in detecting unknown arrival times of received signals, with an especially better computational efficiency. These significant results verify the potential applicability of the bistable system in signal detection field. | | Source: | arXiv, cond-mat/0410412 | | Services: | Forum | Review | PDF | Favorites | |
