Abstract
Las realizaciones aluden a un primer y segundo símbolo piloto que utilizan multiplexacion por division de frecuencia ortogonal (OFDM, por su sigla en inglés). El primer y segundo símbolo piloto puede tener primeros y segundos grupos de frecuencias de portadores permitidas, prohibidas y activas. Los segundos grupos de frecuencias de portadores pueden formarse mediante el desplazamiento de frecuencia de los respectivos primeros grupos por una frecuencia predeterminada, como la diferencia de frecuencia entre los portadores adyacentes. Una realizacion apunta a la parte de traslacion de frecuencia de un primer símbolo piloto recibido por un intervalo de portador en una primer direccion, la parte de traslacion de frecuencia de un segundo símbolo piloto recibido por un intervalo de portador en una segunda direccion opuesta a la primer direccion, y formando una correlacion multiplicando las partes trasladadas de la frecuencia del primer y segundo símbolo piloto por complejos conjugados de partes de los símbolos pilotos sobre los cuales no se ha realizado la traslacion de frecuencia, y sumando los resultados de la multiplicacion.
