Abstract

Las realizaciones apuntan a una modulacion de desplazamiento en fase binaria de un primer símbolo piloto de acuerdo con una secuencia de referencia, y la diferencialmente modulacion de desplazamiento en fase binaria de un segundo símbolo piloto. La secuencia de referencia original y la secuencia de modulacion diferencialmente retardada son combinadas antes de realizar una Transformacion Rápida Inversa de Fourier, insertando un intervalo de seguridad. Las operaciones del receptor son inversas a las operaciones del transmisor, analizadas recientemente. El receptor no tiene que conocer la secuencia de referencia. Las realizaciones apuntan a especificar una pluralidad de semillas que son patrones de bits cada una con bits r y no todas con valor de cero, extendiendo las semillas en las respectivas secuencias aplicando a cada semilla una formula recurrente; y utilizando una de las secuencias como secuencia de peine y utilizando otras secuencias diferentes a la secuencia del peine como patrones de modulacion de desplazamiento en fase binaria.
