Abstract

"EQUIPAMENTO DE CONTROLE DE POTêNCIA, E, PROCESSO PARA CONTROLAR SELETIVAMENTE NìVEIS DE POTêNCIA" Equipamento de controle de potência (54) e um processo associado para uma estação transmissora (32) operável em um sistema de comunicação TDMA (30). A estação transmissora inclui ramais de transmissor (38) para comunicar rajadas de sinais de comunicação durante aberturas de tempo selecionadas (12). Rajadas de sinais de comunicação transmitidas sobre aberturas de tempo adjacentes sobrepõem-se parcialmente, de modo que uma estação receptora (34) é capaz de extrair informação de uma rajada de sinal de comunicação transmitida sobre uma abertura de tempo adjacente.
