Naisargik maps from quaternary to binary spaces can enhance the deletion error-correcting capabilities of Varshamov-Tenengolts and Helberg codes.
Resumé
The paper explores the properties of Naisargik maps, a class of natural maps from the quaternary space (Z4) to the binary space (Z2^2), and their application to Varshamov-Tenengolts (VT) and Helberg codes.
Key highlights:
- VT codes are designed to correct single insertion or deletion errors, while Helberg codes can handle multiple insertion or deletion errors.
- The authors identify 8 Naisargik maps for VT codes and 1 Naisargik map for Helberg codes that exhibit interesting error-correcting properties.
- For the Naisargik images of quaternary VT codes, if two codewords have intersecting one-deletion spheres, then they have the same weight.
- A quaternary Helberg code designed to correct s deletions can effectively rectify s+1 deletion errors when considering its Naisargik image.
- Conversely, an s-deletion correcting binary Helberg code can correct ⌊s/2⌋ errors with the inverse Naisargik image.
- The authors provide mathematical proofs and data analysis to support these observations.
