Abstract
Широкополосный речевой кодер, согласно с одним вариантом осуществления, включает в себя узкополосный кодер и кодер полосы верхних частот. Узкополосный кодер кодирует узкополосную часть широкополосного речевого сигнала как набор параметров фильтра и соответственный кодированный сигнал возбуждения. Кодер полосы верхних частот кодирует, согласно с сигналом возбуждения полосы верхних частот, часть полосы верхних частот широкополосного речевого сигнала для получения набора параметров фильтра Кодер полосы верхних частот генерирует сигнал возбуждения полосы верхних частот путем применения нелинейной функции к сигналу, основанного на кодированном узкополосном сигнале возбуждения, для генерации спектрально расширенного сигнала.
