Title: Method for extracting packet in modified vocorder bypass mode
Inventor: PARK SEONG BEOM
IPC: H04B7/26
Filed: 1998-11-13
Abstract: PURPOSE: A method for extracting packet in modified vocorder bypass mode is provided to decrease a computing amount in a condition that a part of packet is not lost in the cast of performing a mobile-to-mobile encoding by effectively searching two or more preambles and extracting an audio data in which an error is not existed. CONSTITUTION: A preamble in which an effective location is existed is successively searched(s10,s20). An index of a corresponding sub frame is determined(s30). A checksum is computed based on the determined index information when the index of the corresponding sub frame is determined(s40). It is judged as to whether the computed checksum is identical to a received checksum(s50). An audio packet data is processed when the computed checksum is identical to the received checksum(s80). A next sub frame is processed when the computed checksum is not identical to the received checksum(s60,s70,s90).
