Abstract

Receptor para sistema AMRC, destinado para recibir señales correspondientes a sucesiones de símbolos de información de espectro ensanchado por secuencias binarias seudoaleatorias, comprendiendo este receptor K vías de tratamiento (V1, V2, ..., VK) caracterizadas por que al menos una de estas vías (V1) comprende un filtro (20) adaptado a una de sus secuencias seudoaleatorias que han servido para el ensanchamiento del espectro de los símbolos de información y un circuito (12) de recuperación de una señal de reloj símbolo (Hs), comprendiendo cada una de las otras vías (V2, ..., VK) un comparador de desplazamiento (302, ..., 30K) que trabaja con una de las otras secuencias que han servido para el ensanchamiento del espectro de los símbolos de información, estando cada comparador de desplazamiento controlado por una señal de reloj símbolo, que es la señal del reloj (Hs) producida por la vía (V1) que utiliza el filtro adaptado (20).
