发明名称 Method of and apparatus for decoding and processing messages
摘要 A mobile station (104) processes a paging message having information data mapped to a cyclical redundancy check (CRC) error detection code and divided into a plurality of CAC data portions mapped to a plurality of Bose-Chaudhuri-Hocquenghem (BCH) error correction codes. A BCH forward error corrector (FEC) (150) generates a plurality of BCH syndromes (538) to correct single errors that may exist in each of the plurality of CAC data portions (402), and thereby generates a plurality of post-correction CAC data portions (504). A cyclical redundancy check (CRC) error detector (152) detects if an error exists in the plurality of post-correction CAC data portions (504). An error detector (174) detects if BCH syndromes (552-562) corresponding to post-correction CAC data portions (518-528) have values of zero. When the CRC error detector (152) detects an error and the error detector (174) detects that BCH syndromes (552-562) have values of zero, the mobile station (104) processes the paging message and performs a page response function in response to detecting a page.
