Abstract

Описан способ улучшения канальной оценки в системе беспроводной связи. Принимают беспроводной сигнал, который включает в себя множественное число многолучевых компонентов. Потом получают N канальных оценок, где N является любым положительным целым числом больше единицы. Каждая канальная оценка из N канальных оценок отвечает разным многолучевым компонентам из множественного числа многолучевых компонентов. Потом снижаются эффекты интерференции между множественным числом многолучевых компонентов в N канальных оценках.
