Method of, and device for, decoding a repeatedly accesible information stream which is protected by a symbol-correction code.

摘要

@ During the decoding of a code word of an information stream which is protected by a symbol-correction code, first all channel symbols are demodulated; a first indicator flag then indicates whether or not the demodulation is reliable. All code symbols of a code word are subsequently collected, after which the decoding operation commences; the code word is corrected if possible and necessary. The reliability of the correction is indicated by a second indicator flag. When the correction is unreliable, the stream of channel symbols is addressed again. During the latter operation only unreliably decoded code symbols are replaced by new code symbols in order to enable renewed decoding of the code word thus modified.
