Abstract
Az bir miktarda kod kullanılarak bir ses sinyalinin perde periyodundan kaynaklanan tepe noktalarının etrafında yüksek kestirim doğruluğu sağlayan bir frekans alanı zarf dizisini yeniden üretebilen bir kodlayıcı ve bir kod çözücü sağlanmaktadır. Mevcut buluşun bir kodlayıcısı bir periyodik birleşik zarf üretme kısmı ve bir değişken uzunluklu kodlama kısmı içerir. Periyodik birleşik zarf üretme kısmı, bir girdi ses sinyalinden elde edilen bir lineer kestirim katsayısı koduna karşılık gelen bir frekans alanı dizisi olan bir spektral zarf dizisine ve bir frekans alanı periyoduna dayalı olan bir frekans alanı dizisi olan bir periyodik birleşik zarf dizisini üretir. Değişken uzunluklu kodlama kısmı girdi ses sinyalinden türetilen bir frekans alanı dizisi kodlar. Mevcut buluşun bir kod çözücüsü bir periyodik birleşik zarf üretme kısmı ve bir değişken uzunluklu kod çözme kısmı içerir. Periyodik birleşik zarf üretme kısmı bir lineer kestirim katsayısı koduna karşılık gelen bir frekans alanı dizisi olan bir spektral zarf dizisine ve bir frekans alanı periyoduna dayalı olan bir frekans alanı dizisi olan bir periyodik birleşik zarf dizisini üretir. Değişken uzunluklu kod çözme kısmı bir frekans alanı dizisi elde etmek üzere bir değişken uzunluklu kodu kod çözer.
