Abstract

Patente de invenção: "INTERCALADOR E DESINTERCALADOR PARA USO EM UM SISTEMA DE COMUNICAçãO DE TRANSMISSãO DIVERSIFICADA". Aparelhos para um transmissor e um receptor (202) que enriquece o desempenho de um sistema que utiliza intercalação e diversidade de transmissão reordenando a seq³ência de símbolos transmitidos ao longo de diferentes canais de transmissão. Este enriquecimento é consumado fornecendo diferentes funções de embaralhamento em conjunto com os intercaladores (216, 218) e desintercaladores usados com diferentes canais de transmissão, o quais diminuem a probabilidade de perda dos símbolos seq³enciais quando canais ou antenas transmissoras se tornam correlacionados.
