Abstract

Un aparato y método para comunicar datos entre cuando menos dos dispositivos de datos, util para su uso como red de área local inalámbrica, que proporciona comunicacion de datos robusta mediante un canal de comunicacion de radio corrupto por interferencia de trayectorias multiples, particularmente con alto índice de datos. Una modalidad preferida de la invencion representa a los datos como una secuencia de formas de onda de funciones de Walsh (86) codificadas mediante modulacion por difusion de espectro de secuencia directa de seudorruido (83). La codificacion de los datos en funciones de Walsh proporciona una larga duracion de símbolos, permitiendo, mediante esto que la modulacion de la difusion del espectro proporcione suficiente ganancia de procesamiento para superar sustancialmente la interferencia de trayectorias multiples, al mismo tiempo que proporciona un alto índice de datos. La figura más representativa de la invencion es la numero 9.
