Abstract

Bu bulus, sembollerin, varsayilmis sembolleri içeren bölge ile yol tarihi bölgesi arasinda nasil çaprazlanmaya birakilabilecegini ve böylece semböllerin, kismen her iki durumda da bulunabileceklerini tasvir eder. Bu durum, sembolün, sinyal örneklerinin tahmin edilmesi için en önemli kisimlarinin, varsayilmis durumda tutulmasina, buna karsilik geri kalan kisimlarin, yol tarihine geçmesine imkan verir. Bir kod çözücü, sembollerden olusan bir alfabeye ait bilgi sembolleriyle modüle edilen bir sinyalin kodunu çözer. Kod çözücü, alfabe içindeki sembollerin varsayilmasi ve en yüksek olabilirlik göstergesine sahip bilgi sembollerinin bir dizisinin belirlenmesi için bilgi sembollerini içeren alfabe alt-gruplarini varsayan bir maksimum olabilirlik dizisi tahminciyi içerir. Kod çözücü ayrica bir kanal tahminciyi, bir sinyal tahminciyi ve metrik toplayici da içerir.
