institute. The faculty members can also get help from this software by detecting proxy of students also. The Project actually describes the process behind implementing a voice recognition algorithm in MATLAB. The algorithm utilizes the Discrete Fourier Transform in order to compare the frequency spectra of two voices. Chebyshev’s Inequality is then used to determine (with reasonable certainty) whether two voices came from the same person or not. If the two voices matches each other than a present

engineering discipline. It is also the fastest growing technology this century and‚ therefore‚ it poses tremendous challenges to the engineering community. Faster additions and multiplications are of extreme importance in DSP for convolution‚ discrete Fourier transforms‚ digital filters‚ etc. The core computing process is always a multiplication routine; therefore‚ DSP engineers are constantly looking for new algorithms and hardware to implement them. Vedic mathematics is the name given to the ancient

The transmitter is located at one point in space‚ the receiver is located at some other point separate from the transmitter‚ and the channel is the medium that provides the electrical connection between them. The purpose of the transmitter is to transform the message signal produced by the source of information into a form suitable for transmission over the channel. The received signal is normally corrupted version of the transmitted signal‚ which is due to channel imperfections‚ noise and interference

is longer‚ ISI affects at most one symbol‚ and equalization is simplified. In most OFDM implementations any residual ISI is removed by using a form of guard interval called a cyclic prefix. OFDM is essentially identical to coded OFDM (COFDM) and discrete multi-tone modulation (DMT)‚ and is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method. The word "coded" comes from the use of forward error correction (FEC). A large number of closely spaced orthogonal
