взаимнокорреляционная функция
ВКФ
Характеристика, описывающая корреляционные свойства ансамбля сигналов. Численно определяется как произведение одного из сигналов на сдвинутую во времени копию другого. На практике ансамбли сигналов подбираются таким образом, чтобы при их попарной корреляции максимальный выброс ВКФ был бы минимален, что гарантирует низкий уровень взаимных помех. Ср. autocorrelation~.
