  • 摘要:In ar­ti­cle the method for burst er­rors cor­rec­tion in chan­nels with pulse-code mod­u­la­tion is pro­posed. The method is based on the math­e­mat­i­cal op­er­a­tion of bi­nary mul­ti­pli­ca­tion with­out carry. The of­fered method per­mits ac­cel­er­ated per­for­mance with re­duced com­pu­ta­tional com­plex­ity as com­pared to Reed – Solomon codes, as com-pared to known weighed check sum codes while using the same num­ber of bits for error con­trol. The math­e­mat­i­cal back­ground of the pro­posed method is first pre­sented. The pro­ce­dure for burst er­rors is then ex­plained. A nu­mer­i­cal ex­am­ple for pro­ce­dure is given. An an­a­lyt­i­cal com­par­i­son of the com­plex­ity of both the pro­posed and the known meth­ods is pre­sented, that demon­strates the im­prove­ments at­tained. The pro­posed method can find wide ap­pli­ca­tion in mod­ern real time data trans­mis­sion.
