This paper investigates a novel technique called as pilot assisted techniques for PAPR reduction in orthogonal frequency division multiplexing (OFDM). A pilot assisted technique has been implemented in MATLAB for AWGN and Rayleigh channel. PAPR has been found out for AWGN and Rayleigh channel. Also the Bit error rate (BER) vs frame for each channel has been(More)
In the world of social media video processing is very popular. Videos and movies are made up of a temporal sequence of frames and are projected at a proper rate (24 fps for movie and 30 fps for TV) to create the illusion of motion. This means that there exists a high correlation between adjacent temporal frames so that when projected at a proper rate,(More)
— The proposed system introduces a novel framework that can optimize the bandwidth and maintain better visual qualities by performing transcoding on the multimedia contents mainly targeted over the mobile devices. The system designed in Matlab considers both image and video as input file and performs multimedia transcoding considering BMP, GIFF, and JPEG(More)

Transcoding is an inevitable need that is highly required for the current communication system like telemedicine, education, etc. However, it is not devoid of challenges that occur during retrieval end of format incompatibility. Apart from the massive research work in past on designing efficient transcoder architecture, quality of image resolution in(More)
