coding has slower pared with hardwareРdecoding; nevertheless, it has the advantages of lower cost of portable handheldРinstrument with the features of low-power microprocessor and putingРperformance. In the application of test, the technical specification of decoding for codeРmessage meets the requirements expected, so does the handheld tester.РThe innovation of this thesis is proposing the method of software decoding for BaliseРtelegram. An improved optimizing method is introduced for the decoding, on theРpremise of satisfying the design requirements, to avoid the defect of time consumptionРin extreme case. Above all, some achievements are reached about decoding for BaliseРtelegram.РKeywords: Balise telegram, FFFIS for coding and decoding, software decoding, multi-thread techniqueРIVР万方数据
