COMPARATIVE ANALYSIS OF LDPC AND BCH CODES ERROR-CORRECTING CAPABILITIES
Leonid O. Uryvsky, Serhii O. Osypchuk · Information and Telecommunication Sciences · 2014
The error-correcting capabilities of regular LDPC (Low Density Parity Check) codes and BCH (Bose-Chaudhuri-Hocquenguem) codes are examined. The qualitative analysis and the quantitative assessment of error-correcting abilities are performed for LDPC codes with code word length n=1000 bits and BCH codes with code word length n=1023 bits. The code rates of LDPC and BCH codes are determined for a known signal to noise ratio in the gaussian channel; detected code rates are optimal for predefined modulation type and required information reliability on the receiver side.
