Abstract

Система радиосвязи преобразует сигнал временной области во множество частотных сигналов, предназначенных для распределения по множеству поднесущих, предназначенных для передачи. Система радиосвязи изменяет способ распределения множества частотных сигналов по множеству поднесущих на основании информации о мощности передачи.
