Abstract

Mevcut buluş bir iletim kanalı üzerinden iletim için bir kanal veri akışının kanal sembolleri içine bir içeri gelen veri akışının içeri gelen sembollerini kodlamak için bir kodlayıcı ve bunun yanı sıra, bir karşılık gelen kod çözücü ile ilgilidir. Bir bilinen Alamouti kodlayıcı ile karşılaştırmalı olarak hata oranını geliştirmek üzere, bir ölçeklendirilmiş (ve ilave olarak tercihli şekilde döndürülmiş) Alamouti kodlayıcı aşağıdakileri içeren şekilde teklif edilir: kanal sembollerinin çiftleri üzerine içeri gelen sembolleri blok blok haritalandırmak için haritalandırma araçları, haritalandırma kanal sembollerinin sözü edilen iki çiftinin sözü edilen iki içeri gelen sembolün ve/veya sözü edilen iki içeri gelen sembolün en az birinin kompleks eşleniğinin ölçeklendirilmiş versiyonlarını içereceği şekilde kanal sembollerinin iki çifti üzerine haritalandırmak için düzenlenir, sözü edilen ölçeklendirilmiş versiyonlar birden farklı bir mutlak değer ile bir ölçeklendirme faktörüne sahip olan ve en az iki parça ile parça-bakımından lineer olan bir ölçeklendirme fonksiyonunun uygulanması aracılığıyla elde edilirler ve sözü edilen kanal sembollerini çıktılamak için çıktılama araçları vardır.
