Abstract

Se describe un circuito de vía de revestimiento para transmitir información a través de un bloque de vías férreas. En una modalidad, uno de una pluralidad de códigos asignados a un par receptor/transmisor se usa para representar cada segmento de información (que puede ser uno o más bits) de una señal de información. En otra modalidad, los bits de la señal de información se transmiten entre repeticiones periódicas de un código asociado con el par transmisor/receptor. La modulación puede realizarse usando una técnica clave de cambio de frecuencia. Los circuitos de vía pueden conectarse para información retransmitida entre los bloques adyacentes de la vía.
