H03M 13/37 Decoding methods or techniques, not specific to the particular type of coding provided for in groups H03M13/03 - H03M13/35
Introduced: January 2000
Title
Titles differ between systems:
IPC: Decoding methods or techniques, not specific to the particular type of coding provided for in groups
CPC: Decoding methods or techniques, not specific to the particular type of coding provided for in groups H03M13/03 - H03M13/35
Full Title
Full titles differ between systems:
Coding, decoding or code conversion, for error detection or error correction; Coding theory basic assumptions; Coding bounds; Error probability evaluation methods; Channel models; Simulation or testing of codes > Decoding methods or techniques, not specific to the particular type of coding provided for in groups
Coding, decoding or code conversion, for error detection or error correction; Coding theory basic assumptions; Coding bounds; Error probability evaluation methods; Channel models; Simulation or testing of codes (error detection or error correction for analogue/digital, digital/analogue or code conversion H03M1/00 – H03M11/00; specially adapted for digital computers G06F11/08; for information storage based on relative movement between record carrier and transducer G11B, e.g. G11B20/18; for static stores G11C) > Decoding methods or techniques, not specific to the particular type of coding provided for in groups H03M13/03 - H03M13/35
CPC subdivides this area 4x more granularly than IPC with 10 additional codes.
10 codes are CPC-only extensions.
2 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2000.
