Latest Patents

Coulon's latest patents include a method for correcting messages containing bit stuffing. This invention relates to a method that corrects a message generated by transforming an initial message and inserting bit stuffing into the transformed message. The method involves providing an observation sequence containing the message to be corrected. A number of path hypotheses are generated via a trellis diagram associated with the transformation. The nodes of the trellis diagram represent states of a finite-state machine capable of transforming the initial message, while the branches represent possible transitions between nodes. Certain branches represent conditional transitions that may occur only when bit stuffing is present. During the generation of a path hypothesis, bit stuffing is detected, and the branches taken are those associated with the detected bit stuffing. Ultimately, the most likely path hypothesis relative to the observation sequence is retained.

Another significant patent is related to a decoding method and decoder. This method pertains to decoding a sequence of symbols generated by calculating a CRC value for an initial message, combining the initial message and the CRC value to produce a transformed message, and encoding the transformed message. The decoding process involves generating a number of path hypotheses via a trellis diagram corresponding to a finite-state machine that includes both the encoder and the CRC generator, supplied with the same input. A preferred embodiment of this method adapts the trellis diagram to account for bit stuffing that may have been inserted in the transformed message before encoding.
