Descripción del Proyecto

LDPC-codes is a collection of programs and modules intended to support research and education concerning Low Density Parity Check (LDPC) codes. The decoding algorithm for LDPC codes is related to that used for Turbo codes, and to probabilistic inference methods used in other fields. Variations on LDPC and Turbo codes are currently the best practical codes known, in terms of their ability to transmit data at rates approaching channel capacity with very low error probability.

Esta versión incluye funciones aleatorias de glibc estandarizarles. Agrega una opción -f para codificar y decodificar que fuerzas vaciado después de escribir cada bloque. Agrega una opción - z para pchk a alist a suprimir la salida de la fila 0 y columna índices esa almohadilla hasta el número máximo utilizado. Documenta las opciones previamente indocumentados -t para pchk a alist y alist a pchk. Limpiezas de correcciones y código. Se quitó la licencia de la cláusula de publicidad.
