Abstract
Maximum Likelihood Convolutional Decoding, which is used by the Deep Space Network for short constraint-length convolutional codes, assumes that all strings of information bits are equally likely. In some cases, like image data, this is not the case. We examine the use of information about an adjacent pixel in decoding convolutionally encoded Voyager images, and discover that, in a region of interest, as much as 2 dB may be gained.
