Abstract

"MéTODO E EQUIPAMENTO PARA DESIGNAçõES DE POTêNCIA POR DIVISãO NO TEMPO EM UM SISTEMA DE COMUNICAçãO SEM FIO". Em um sistema de comunicação de dados CDMA capaz de transmitir dados com taxa variável, uma designação de potência por divisão no tempo reduz ciclicamente o nível de potência da portadora para pelo menos um setor para reduzir a interferência nos setores vizinhos. A estação base determina uma designação de potência por divisão no tempo para cada setor e gera sinais de acordo com a designação de potência. A unidade móvel (700) gera coeficientes de filtro correspondentes a cada nível de potência. A unidade móvel estima o Sinal de portadora/Interferência (C/I) para determinar uma taxa de dados para cada nível de potência. As iterações anteriores do equalizador (710) são armazenadas e utilizadas para refinar as estimativas futuras.
