Abstract

La presente divulgación incluye sistemas de comunicación inalámbrica con acceso múltiple por división de código con prevención de interferencia (CDMA-LA); En una realización, el sistema de comunicación inalámbrica incluye una pluralidad de transmisores y una pluralidad de receptores. Al menos un transmisor de la pluralidad de transmisores está configurado para detectar segmentos desocupados de ocupación del espectro de interferencia en uno de la pluralidad de receptores, y difundir energia de una señal transmitida en forma no uniforme a través de un ancho de banda de canal que es mas ancho que una banda ancha de información de la señal transmitida utilizando una pluralidad de segmentos espectrales no continuos que corresponden a los segmentos desocupados de la ocupación del espectro de la interferencia en uno de la pluralidad de receptores. Al menos un receptor de la pluralidad de receptores está configurado para Ileyar a cabo un proceso de demodulación de integración coherente de energía de la señal transmitida sobre la pluralidad de segmentos espectrales no continuos.
