Abstract

Un método de disposición de piloto en un sistema de comunicación por radio móvil mediante el cual, para evitar un problema que la deficiente precisión de CQI afecte la programación de la disposición de canal para ocasionar que se deteriore el rendimiento, una banda de frecuencia de trabajo se divide en una pluralidad de bandas predeterminadas y se realiza multiplexión de división de tiempo; un símbolo piloto conocido se inserta en las bandas de frecuencia predeterminadas en intervalos de referencia predeterminados; además, el símbolo piloto conocido se inserta en al menos una de las bandas de frecuencia predeterminadas en intervalos menores que los intervalos de referencia predeterminados y dispuestos.
