Abstract

UNA ESTACION DE BASE ESTABLECE CANALES AMRC DEFINIDOS CADA UNO POR UNA SECUENCIA DE EXTENSION RESPECTIVA (CS, C1.....CM) MODULANDO BITS DE INFORMACION A TRANSMITIR (DS, D1...DM) PARA FORMAR UNA SEÑAL DE CANAL RESPECTIVA (SCS, SC1....SCM).LAS DIFERENTES SEÑALES DE CANALES SE COMBINAN Y SE MODULAN SOBRE UNA FRECUENCIA PORTADORA DE MANERA A PRODUCIR UNA SEÑAL DE RADIO CON MODULACION DE FASE EMITIDA HACIA ESTACIONES MOVILES. CADA SECUENCIA DE EXPOSICION (CP, CS, C1, ...CM) NO COMPRENDE MAS QUE UNA COMPONENTE REAL. PARA PRODUCIR LA SEÑAL DE RADIO,SE APLICA UN DESFASE RELATIVO ENTRE DIFERENTES SEÑALES DE CANALES (SCP, SCS, SC1,..... SCM).
