Nowadays, biometric identification technology is used for authentication purposes. Of that, Multimodal biometric authentication systems are gaining much popularity. In this paper, we propose a system that can be used in place of ATM cards. This ensures a sense of security as well as privacy to the user. Here, partial palmprint and partial palmvein are(More)
A turbo block code (TBC) technique for improving the performance of a multi-carrier code division multiple access (MC-CDMA) system in terms of bit error rate (BER) is proposed in this paper. The objective of this work is to develop a coding scheme that generates low BER code-words. By implementing a time domain TBC, designed using powerful low density(More)

Polar codes have emerged as an important error correction codes due to their capacity achieving property and also seen them as a major breakthrough in coding theory. For (n, k) polar codes, the delay in partial sum network (PSN) implementation are a bottleneck for designing high speed polar decoder. Therefore, an efficient PSN updating algorithm and its(More)
— Breast cancer detection remains a subject matter of intense and also a stream that will create a path for numerous debates. Mammography has long been the mainstay of breast cancer detection and is the only screening test proven to reduce mortality. Computer-aided diagnosis (CAD) systems have the potential to assist radiologists in the early detection of(More)
Audio classification serves as the fundamental step towards the rapid growth in audio data volume. Automatic audio classification is very useful in audio indexing; content based audio retrieval and online audio distribution. The accuracy of the classification relies on the strength of the features and classification scheme. In this work both, time domain(More)
Multi carrier code division multiple access (MC-CDMA), a strong contender for future mobile communication is a combination of orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA). Turbo coding technique can be used for improving the performance of MC-CDMA system in terms of bit error rate (BER). The objective of this(More)
Wireless communications using Multiple-Input Multiple-Output (MIMO) links has emerged as one of the most significant breakthroughs in modern communications because of the huge capacity and reliability gains promised even in worst fading environment. This paper presents the optimized behaviour of MIMO systems over Rayleigh and Rician Fading channel(More)
