Abstract
Alt taşıyıcıların alt çerçevelerine ve sembol pozisyonlarına sahip olan bir çerçeve yapısı içerisine pilot dizilerinin (bir kanalın tahmin edilmesinde bir alıcıya destek olmak için) yerleştirilmesi için bir yöntem, cihaz, bilgisayar programı ürünü, entegre devre ve sistem tarif edilmiştir. Ortak pilot dizilerinin konumları önceden belirlenir ve şunları içerir: 1) her alt çerçevede, bir pilot dizisi, en az iki kademeli alt taşıyıcının her biri için bir birinci sembole yerleştirilir ve 2) en az bir alt çerçevede, en az bir pilot dizisi, birinci sembol pozisyonu dışındaki bir pozisyona ve en az iki kademeli alt taşıyıcının herhangi birinden başka bir alt taşıyıcıya yerleştirilir. Çerçeve içerisindeki konumları önceden belirlenmiş olmayan özel pilot dizileri, bir kablosuz bağlantı üzerinden alınmış olan bir kanal kalitesi işaretine göre yerleştirilir. Ortak pilot dizileri, bir veya iki iletim antenine ilişkin olabilir ve özel pilot dizileri, üçüncü ve dördüncü iletim antenlerinin eklenmesine imkan verebilir.
