Abstract

Прийняті аудіодані можуть включати перший набір частотних коефіцієнтів і другий набір частотних коефіцієнтів. Просторові параметри щонайменше для частини другого набору частотних коефіцієнтів можуть оцінюватися щонайменше частково на основі першого набору частотних коефіцієнтів. Оцінювальні просторові параметри можуть застосовуватися до другого набору частотних коефіцієнтів для генерування модифікованого другого набору частотних коефіцієнтів. Перший набір частотних коефіцієнтів може відповідати першому діапазону частот (наприклад, діапазону частот окремих каналів), а другий набір частотних коефіцієнтів може відповідати другому діапазону частот (наприклад, діапазону частот зв'язаних каналів). Комбіновані частотні коефіцієнти складеного каналу зв'язування можуть ґрунтуватися на частотних коефіцієнтах двох або більше каналів. Можна обчислити коефіцієнти взаємної кореляції між частотними коефіцієнтами першого каналу й комбінованими частотними коефіцієнтами.
