Synopsis

This book focuses on Image Transmission through MC-CDMA Channel in low SNR environment. The whole MC-CDMA system is composed of 5 main components which are the compressor, transmitter model, channel model, receiver model and decompressor. The system involves multi-user image transmission. The original image with PPM or PGM file extension is compressed by using JPEG2000 standards (Wavelet Image Compression). The compressed image is inserted into the digital system and the image data is transmitted through the system. The multi-user image data are received in the output of the receiver. Then this image goes to the decompressor. The multi-user image data are decompressed into an image with PPM or PGM file extension. The reconstructed image for JPEG2000 is compared with the original image by using PSNR and RMSE. The difference between the quality of the original image and the reconstructed image is observed.To examine the quality of the reconstructed images at low SNR MC-CDMA channel, the channel?s SNR is varied from 10,8,6,5, and finally to 4.At each SNR value, two test images were transmitted and its reconstructed image were compared with original image by using PSNR and RMSE.
