Abstract
Se proporciona un sistema de comunicación con una pluralidad de estaciones móviles y una estación base. Una estación móvil realiza un canal piloto compuesto de un código Cazac correspondiente a una señal que tiene una pluralidad de componentes de frecuencia, en una banda predeterminada colocada en paralelo una con la otra a una distancia constante. Una estación móvil transmite una señal de transmisión que incluye tal señal de acuerdo con una señal de programación de horario. La estación móvil también realiza su propia señal de transmisión, correspondiente a la señal de transmisión de otras estaciones móviles que utilizan diferentes bandas de una banda de aquella de la propia señal de transmisión, con el fin de que la primera sea ortogonal con la última sobre un eje de frecuencia. Una estación base calcula una diferencia entre una señal de recepción y una réplica del canal piloto, para inferir un canal. La estación base descodifica la señal de recepción mediante el uso de un resultado de inferencia de canal. La réplica de la señal piloto es generada el corresponder el canal piloto compuesto del código Cazac con la banda predeterminada colocada en paralelo una con la otra a la distancia constante.
