Abstract
[Abstract] This work deals with the transmission of images, previously coded using the Embedded Zerotree Wavelet (EZW) transform, over wireless systems in which
Space-Time Coding (STC) is used. It is shown how the system performance, measured in terms of Peak Signal to Noise Ratio (PSNR), can be improved using bit allocation strategies that take into account the special structure of the EZW bitstream, where the bits firstly allocated are associated to the lowest frequency subbands, and therefore, an error–free transmission of such bits will be crucial to appropriately
recover the transmitted image.
