To transfer reliably information in erasure channels, LT (Luby Transform) codes were created, they are part of the main class of fountain codes, this codes don’t have fixed rate, in other words, they have a versatile code rate. This thesis address to the study of images transmission through noisy channel, AWGN (Aditive White Gaussian Noise) using LT codes. We investigated the performance using a BPSK modulation, two schemes were tested: A scheme of channel that includes deletion (BESC) and another that was proposed, using a Hamming code in series with a LT code. The LT-Hamming scheme present a gain code larger than BESC scheme and convolutional codes of similar characteristics. Was tested LT-Hamming scheme for different types of images on AWGN channel using the SPIHT technique for images compression. To obtain an objective measure of image quality was used the PSNR (Peak Signal Noise Ratio) and some images were presented in order to analize its quality through visual inspection given that LT code is a versatile for what concern the code rate it was proposed a method to assign different protection levels to the code information, UEP (Unequal Error Protection).
