SYSTEM AND METHOD FOR DECODING A MESSAGE USING A PRIORI INFORMATION

摘要

Methods and systems are disclosed for decoding digital data received by a correspondent device (154) over a communication channel (156). The data includes a component corresponding to a plurality of values unknown to the correspondent device (154) and a component corresponding to one or more values known a priori by the correspondent device (154). To perform decoding, the correspondent device (154) retrieves from memory (162) at least one of the one or more known values. The correspondent device (154) then applies a statistical measure using the known value(s) to estimate the location of the component corresponding to the one or more known values. The one or more known values and the estimated location of the component corresponding to the one or more known values are then used by a decoder (160) to assist in decoding the data.
