Traditional detection algorithms, such as the GLRT and AMF, require a training data set. Recently, single data set (SDS) algorithms, namely the GMLED and MLED, have been proposed to deal with the case where training data may not be available. In this paper, we examine the performance of these algorithms under template (or steering vector) mismatch. We identify three types of mismatch, namely the spatial steering vector mismatch, temporal steering vector mismatch and mismatch in both steering vectors. In each mismath case we derive the expected signal to noise ratio loss with respect to the corresponding matched case. Simulation results are given which show that the SDS algorithms are more sensitive to mismatch mainly due to the interaction between the signal and subspaces estimation. However, this increased sensitivity to mismatch is closely related to the ability to resolve close signals. Therefore, the SDS algorithms exhibit higher resolution","PeriodicalId":421826,"journal":{"name":"Proceedings of the Fifth IEEE International Symposium on Signal Processing and Information Technology, 2005.","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121548773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These goals have led to the development of a wide range of schedulers that are characterized by deterministic decision making. Randomness in decision making enables high performance scheduling as well as fair treatment of requests, when used appropriately. However, it has been proven to be costly in switching environments, which require high speed decisions, as the experience with the first randomized algorithm, namely PIM, is shown. In this paper, we introduce a class of practical scheduling algorithms that employ randomness in a fashion that leads to fast, low cost implementations. The class of algorithms, named random on-line matching (ROLM), employs randomness effectively, calculating maximal matchings and thus, leading to high performance schedulers with optimal mean service time that outperform significantly the competitive deterministic schedulers; furthermore, it employs randomness efficiently, resulting to schedulers that can accommodate effectively high-speed links","PeriodicalId":421826,"journal":{"name":"Proceedings of the Fifth IEEE International Symposium on Signal Processing and Information Technology, 2005.","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121834159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Including the biophysical complexity of the wave motion in the cochlea and considering all terms of the motion equation, the new model can evaluate the auditory spectrum using the Basilar membrane (BM) displacement and the inner hair cells' (IHCs) firing rate for all input signals, including speech. We employ the partial differential motion equations of the BM and its parameters measured for the human auditory system, and design an algorithm which uses short time Fourier transform (STFT) to compute the output for speech stimulus. The idea is to isolate the input signal in the vicinity of a time-window and try to follow the changes in its frequencies and their influences on the signal perceived by the auditory system. The new model includes the nonlinearity action of outer hair cells (OHCs) and provides a new auditory spectrum for speech inputs in the real time domain which reflects a proper view of propagating signal in the cochlea. Despite most of the previous models this model can track the effects of high formant frequencies in the human cochlea as well. This model is a new signal processing tool for studying the response of the auditory system to transient signals which is highly demanded in various speech enhancement and audio coding algorithms","PeriodicalId":421826,"journal":{"name":"Proceedings of the Fifth IEEE International Symposium on Signal Processing and Information Technology, 2005.","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133618042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
