The impetus for this new feature extraction technique comes from the filter bank summation method of STFT using Nyquist filter bank. The focus of this work is on applications which yield higher identification accuracy without increasing the computational effort. We have proposed this transform from speaker identification perspective. The proposed transformation can be used for both uniform width filter bank and non-uniform width filter bank representation. A complete experimental evaluation was conducted on a database of 61 speakers with Gaussian mixture speaker model. This new feature extraction technique has been compared with Mel-frequency cepstral coefficient (MFCC) feature. The average accuracy of MFCC feature set was 88.05%. The average accuracy of proposed feature set with uniform width filter bank and non uniform width filter bank was 90.24% and 90.42% respectively. The average accuracy was 92.26% after score level fusion of uniform width filter bank feature and non uniform width filter bank feature of the proposed transformation. The discrimination capability of the proposed feature sets have been evaluated statistically using F-ratio and J-measure. Experimental results show that the proposed feature sets have higher discrimination capability compared to MFCC feature set.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121682031","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}

However, such a filter requires quite a large number of filter coefficients as compared to an Infinite duration Impulse Response (IIR) filter and hence leads to greater computational complexity. In this paper, an efficient algorithm has been proposed for the minimization of the number of coefficients of standard Raised Cosine (RC) pulse-shaping filter of different lengths, without affecting its performance to a great extent. The performance of the designed filter has been studied in terms of its impulse response as well as magnitude response. The designed FIR filter has also been used as a pulse-shaping filter in a Quadrature Phase Shift Keying (QPSK) modulated system and its performance has been studied in terms of the system Bit Error Rate (BER) value. From the simulation results it has been established that the newly proposed filter provides a significant reduction in the number of tap coefficients without much degradation in its performance.","PeriodicalId":109071,"journal":{"name":"2010 Annual IEEE India Conference (INDICON)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127697960","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}
