Full Title

Full titles differ between systems:

IPC:

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, forward error correction or error protection, not provided for in groups

CPC:

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) > Error detection, forward error correction or error protection, not provided for in groups H03M13/01 - H03M13/37

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 2000.
