Abstract

Se proporciona en la presente un método y aparato para codificación turbo con un entrelazador libre de contienda. Durante la operación se recibe un bloque de entrada de tamaño K'. El bloque de entrada original y el bloque de entrada entrelazado se codifican para obtener un bloque de palabra código, en donde el bloque de entrada original se entrelaza usando un entrelazador de tamaño K' y una permutación n(i) = (¿1 xi+ ¿2 x i2)mod K', donde 0 = i = K'-1 es el índice secuencial de las posiciones de símbolo después del entrelazado, p(i) es el índice de símbolo antes del entrelazado correspondiente a la posición i, K' es el tamaño entrelazador en símbolos, y /i y /2 son los factores que definen el entrelazador. Los valores de K', ¿1, ¿2 se toman de al menos una fila de una tabla. El bloque de palabra código se transmite a través del canal.
