Speech Hiding Techniques DWT and LSB Algorithm For Better SecurityBy Akanksha Lohia, Sarita Singh Bhadauria
Abstract: Abstract— The proposed paper presents a comparison analysis between Discrete Wavelet Transform(DWT) and Least Significant Bit (LSB) algorithm such that which algorithm gives better security for host audio file.The LSB algorithm uses only small part(LSB) of complete image while in DWT algorithm we use 2 level DWT for audio and 1 level for audio.So the paper describes the comparison of these methods for speech hiding and extraction on the basis …

Digital Pulse Compression Waveform Generation by Using of Digital Matched FilterBy devesh Tiwari, Sarita Singh Bhadauria
Abstract: Digital pulse compression is the technique for detection of the targets through radar. It is done by Matched Filter in signal processing system. The presence of signal with noise is compressed. At some finite interval of time the high peak amplitude of signal with narrow bandwidth gives the idea of the number of targets present away from the radar. Matched filter gives the signal to noise ratio at the receiver …

Congestion Control by Transmission power in Ad-Hoc Network using Fuzzy LogicBy Soni Kumari, Sarita Singh Bhadauria, Laxmi Shrivastava
Abstract: As a result of the growth in communication technologies, mobile ad hoc network boosting its capability in terms of ad hoc communication between the mobile nodes. The mobile ad hoc networks do not have any predefined infrastructure so the mobile nodes which want to communicate with each other immediately form the network topology and initiates the request for data packets to transmit or receive. But in mobile ad hoc networks …
