Abstract

Procedimiento de codificación espaciotemporal para sistema de transmisión UWB que incluye al menos dos elementos radiativos, codificando dicho procedimiento un bloque de símbolos de información (S=(a1, a2, ... , ap2)) que pertenecen a un alfabeto de modulación 2-PPM o de modulación compuesta 2-PPM-M'-PAM con M'≥2, en una secuencia de vectores (si,j, Ωsi,j) destinándose los componentes de un vector a modular una señal UWB de impulso para un elemento radiativo de dicho sistema y para un intervalo de transmisión dado (Tf), caracterizado porque dichos vectores se definen como los elementos de la matriz:# **(Ver fórmula)** definida a una permutación más o menos de sus líneas y/o de sus columnas, correspondiendo una línea a un intervalo de transmisión y una columna a un elemento radiativo, donde Ω es una matriz de rotación de ±π/2, P es el número de elementos radiativos y **(Ver fórmula)** con un margen de aproximadamente ±10% donde I2 es la matriz identidad de formato 2x2, ⊗ es el producto tensorial, al, l=1,...,P2 son los símbolos de información, Rj es un vector línea de dimensión P que corresponde a la jésima línea de una matriz ortogonal R que genera la red de puntos Λ={uΘ|u∈ZP} con **(Ver fórmula)** donde θp, p=0,...,P-1, son P raíces distintas de un polinomio de grado P de coeficientes racionales.
