Abstract

Раскрывается способ оценки сигнала, который передается, в системе беспроводной связи. Принимается беспроводной сигнал, который содержит пилотный канал и, как минимум, один другой канал. Сигнал, который передается, оценивается с помощью эквалайзера и беспроводного сигнала, который принимается. Выводы фильтра эквалайзера согласовываются при помощи использования канальной оценки. Канальная оценка вычисляется из пилотного канала. Пилотный канал и, как минимум, один другой канал разделяются.
