Abstract

Buluş, frekans bölgesinde karmaşık tahmin kullanılarak stere kodlama ve kod çözmeye yönelik yöntemler ve cihazlar sağlamaktadır. Bir yapılandırmada, karmaşık tahmin kodlama ile kodlanan ve iki girdi kanalının birinci frekans bölge gösterimlerini içeren bir girdi stereo sinyalden bir çıktı stereo sinyal elde etmeye yönelik bir kod çözme yöntemidir, şu yukarı karıştırma adımlarını içermektedir: (i) bir birinci girdi kanalının bir ikinci frekans-bölgesi gösteriminin hesaplanması; ve (ii) birinci girdi kanalının birinci ve ikinci frekans-bölgesi gösterimlerine, ikinci girdi kanalının birinci frekans-bölgesi gösterimine ve bir karmaşık tahmin katsayısına dayanarak bir çıktı kanalının hesaplanması. Yukarı karıştırma, kontrol verisine yanıt olarak askıya alınabilmektedir.
