Abstract

In lossless compression of the ultraspectral sounder data, the arithmetic coder is often used as the last stage of the compression scheme. While the arithmetic coder is good at compressing arbitrarily close to the entropy of the source, it is also known for its severe weakness to transmission noise. Even a single bit error in the transmission process can cause havoc and make the subsequent decoded stream completely useless. To cope with it, this paper adopts an arithmetic coder with a forbidden symbol and uses the maximum a posteriori (MAP) technique for decoding. Based on the ultraspectral sounder data, evaluation on the error correction capability of this error-resilient arithmetic coder will be reported.
