- W2041636232 abstract "The use of two-dimensional (2-D) block transform image coding using the discrete cosine transform (DCT) is considered in the presence of channel errors. This technique has proven an efficient and readily implementable source coding technique in the absence of channel errors. In the presence of channel errors, however, the performance degrades rapidly requiring some form of error-control protection if reasonable quality image reconstruction is to be achieved. Unfortunately, channel coding can be extremely wasteful of channel band-width if not applied judiciously. This paper describes an approach which provides a rationale for combined source-channel coding which results in improved quality image reconstruction without sacrificing transmission bandwidth. This approach is shown to result in a relatively robust design which is reasonably insensitive to channel errors and yet provides performance approaching theoretical performance limits." @default.
