Compression of an Image and Performance over AWGN Channel by applying PSK along with DCT Transform
Prof. K. S. Solanki · International Journal for Research in Applied Science and Engineering Technology · 2018
Transmission of multimedia, especially transmission of uncompressed image/video requires immense quantity of storage and high reliability. Analogues to this large transmission bandwidth required for transmission of uncompressed image/video information, over the network. In Wavelet transform image compression is one of the considerable characteristic. Some of the transform methods are used for image compression and gives sustainable reforms in the quality of image. This paper show round the influence of an image transmission via AWGN channel using PSK (Phase Shift Keying), QAM (Quadrature Amplitude Modulation) and also transmission of uncompressed image via AWGN channel. Most of the time less storage and time have required to compressed image. For the transmission of simple image & compressed image through AWGN channel, offered method is used to confer lesser BER (Bit Error Rate) and increase PSNR (Peak Signal to Noise Ratio) for different SNR (Signal to Noise Ratio) values. By plotting all the parameters we measure the performance and with the help of result it can be clear that the precision is maintain by the proposed scheme.
