Abstract

Изобретение относится к способу и устройству для регулирования мощности сигналов, излучаемых передающими устройствами, в роли которых выступают абонентские или базовые станции сотовой радиосистемы, использующие один и тот же канал. Описана итерационная процедура, для которой ослаблены требования синхронности и координированности между передающими устройствами. Мощности сигналов сходятся с геометрической скоростью к оптимальным значениям, которые определяются как минимальные мощности, требуемые для поддержания отношения мощности несущей сигнала к мощности взаимной помехи, превышающего некоторую назначенную величину, выбранную из соображений качества связи. В результате ослабления требований синхронности и координированности удается обойтись без дорогих устройств высокоточной синхронизации, что приводит к снижению стоимости управления мощностью.
