Abstract
La deteccion, elusion y/o correccion de patrones de perforacion problematicos en corrientes de bits de paridad utilizados cuando se implementan codigos turbo perforado se logra sin tener que evitar velocidades de codigos deseables. Esto permite la identificacion/elusion de regiones de una performance de codigo Turbo relativamente pobre. La correccion anticipada de errores que comprende codificacion Turbo y perforacion logra una relacion funcional uniforme entre cualquier medida de performance y la velocidad de codificacion efectiva resultante de la combinacion del codigo de menor velocidad que se genera por el codificador Turbo con perforacion de los bits de paridad. En una forma de realizacion, se implementan metodos para corregir/evitar degradaciones debidas a codificacion Turbo por interacciones de perforacion cuando se emplean dos o mas etapas de adaptacion de velocidad.
