For the blessing of World Wide Web, the corpus of online information is gigantic in its volume. Search engines have been developed such as Google, AltaVista, Yahoo, etc., to retrieve specific information from this huge amount of data. But the outcome of search engine is unable to provide expected result as the quantity of information is increasing(More)
— Like many wireless systems, Orthogonal Frequency Division Multiplexing (OFDM) needs proper allocation of limited resources such as total transmit power and available frequency bandwidth among the users to meet their service requirements. In this paper, different versions of two evolutionary approaches, Differential Evolution (DE) and Particle Swarm(More)
This paper presents a class of pipelined CORDIC architectures for the LMS-based transversal adaptive filter. For this, an alternate formulation of the LMS algorithm is considered, obtained by expressing the mean square error as a convex function of a set of angle variables that are monotonically related to the filter tap weights. The proposed architectures(More)
A systolic array architecture for the adaptive decision feedback equalizer (ADFE) is proposed in this paper which is based on an algebra developed earlier by Kung et al [5]. Two basic processing cells that are computationally equivalent and easy to realize are used to construct the main body of the array. To satisfy all the desirable features of a systolic(More)
A method has been proposed in this paper for Bengali news documents summarization which extracts significant sentences using the four major steps (a) preprocessing, (b) sentence ranking, (c) sentence clustering, and (d) summary generation. The noticeable feature of this method is the incorporation of the sentence frequency where redundancy elimination is a(More)
