Abstract

EL SISTEMA DE RADIO MOVIL CELULAR COMPRENDE AL MENOS DOS ESTACIONES BASE Y AL MENOS UNA UNIDAD MOVIL DISPUESTA PARA COMUNICAR CON LAS ESTACIONES BASE MEDIANTE UN MEDIO DE RADIO. CADA ESTACION BASE INCLUYE UNOS ELEMENTOS PARA DETECTAR LA ENERGIA DE SEÑALES RECIBIDAS, UNOS ELEMENTOS PARA GENERAR UN BIT DE SEÑALIZACION DE CONTROL DE ENERGIA PARA CONTROLAR LA AMPLITUD DE UNA SEÑAL DE ENERGIA, Y UNOS ELEMENTOS PARA TRANSMITIR LA SEÑAL DE ENERGIA A LA UNIDAD MOVIL. LA UNIDAD MOVIL INCLUYE UNOS ELEMENTOS PARA RECIBIR LOS BITS DE CONTROL DE ENERGIA Y UNOS ELEMENTOS PARA CONTROLAR LOS BITS DE CONTROL DE ENERGIA PARA IDENTIFICAR LA ESTACION BASE QUE ENVIA UN NUMERO MAYOR DE BITS DE CONTROL SOBRE UNA TRAMA DE TRANSMISION, INDICANDO QUE ESTACION BASE HA RECIBIDO LA MAYOR MEDIA DE SEÑAL DE ENERGIA SOBRE LA TRAMA DE TRANSMISION.
