A new technique for text-independent speaker recognition for noisy speech is presented. This technique is based on finding the ratio of the singular values of the feature vectors of the unknown speaker and each of the N reference features stored in the constructed database. The th i reference feature that gives the largest ratio is considered the feature of(More)
In this paper, a new technique is presented to design quadrantally symmetric 2-D IIR filters. This technique is based on two steps: First, the 2-D impulse response matrix (Hankel matrix) is decomposed by the SVD (Singular Value Decomposition) to k parallel branches, each branch is composed of two cascaded singleinput single-output (SISO) 1-D FIR filters.(More)
A low-cost coplanar waveguide fed compact ultrawideband (UWB) antenna with band rejection characteristics for wireless local area network (WLAN) is proposed. The notch band characteristic is achieved by etching half wavelength C-shaped annular ring slot in the radiating patch. By properly choosing the radius and position of the slot, the notch band can be(More)
In this paper, we present an automatic Qari Recognition system based on text-independent speaker recognition technique using Mel-Frequency Cepstral Coefficients. Our test database of 200 samples consisted of recordings by 20 reciters and we achieved 86.5% recognition rate for clean samples. The recognition rate is also tested for noisy samples of 25 dB to 0(More)
