Abstract
Se revela un método para controlar los niveles de potencia de transmision en un sistema celular de espectro esparcido o CDMA, en el cual la decision deaumentar o disminuir el nivel de potencia de transmision de una estacion movil o de una estaciond e base y la cantidad de tal aumento o disminucion, se basaen la combinacion ponderada de multiples factores que indican las condiciones de canal existentes. Por ejemplo, la ponderacion se puede fijar de acuerdo conla confiabilidad de cada factorde condicion de canal implicado.
