Sequence estimation, i.e. using statistical methods for the reconstruction of the original codes

Introduced: January 2000

Title

Titles differ between systems:

IPC: Sequence estimation, i.e using statistical methods for the reconstruction of the original codes

CPC: Sequence estimation, i.e. using statistical methods for the reconstruction of the original codes

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 > Decoding methods or techniques, not specific to the particular type of coding provided for in groups > Sequence estimation, i.e using statistical methods for the reconstruction of the original codes

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) > Decoding methods or techniques, not specific to the particular type of coding provided for in groups H03M13/03 - H03M13/35 > Sequence estimation, i.e. using statistical methods for the reconstruction of the original codes

CPC subdivides this area 12x more granularly than IPC with 11 additional codes.

11 codes are CPC-only extensions.

IPC defines codes here since 2000.
