Abstract

Ses ve konuşmadan en az birini içeren bir sinyalin kodlanmasına yönelik bir usul olup, usul şunları içerir: sinyalin bir önceden ayarlanmış frekansa göre önceden ayarlanmış frekanstan yüksek bir banda karşılık gelen bir yüksek frekanslı sinyal ve önceden ayarlanmış frekanstan düşük bir banda karşılık gelen bir düşük frekanslı sinyal halinde bölünmesi; düşük frekanslı sinyaldeki tüm alt-bantların bir frekans bileşeninin kodlanması; yüksek frekanslı sinyalde yer alan bir frekans bileşenine göre yüksek frekanslı sinyalde bir bit tahsis edilen bir alt-bandın tespit edilmesi; ve yüksek frekanslı sinyalde tespit edilen alt-bandın bir frekans bileşeninin kodlanması.
