The purpose of this work is to associate the channel encoder called ‘trellis-coded modulation with Ungerboeck-Gray mapping’ (TCM-UGM) to ‘space–time block code’ (STBC), in order to study its performance to correct the transmission errors of a JPEG image. The…

In the first paper of this series, we propose a multi-resolution theory of Fourier spectral estimates of finite duration signals. It is shown that multi-resolution capability, achieved without further observation, is obtained by constructing multi-resolution…
