Abstract
"MéTODO E APARELHO PARA CODIFICAR OS SINAIS EM SALTO DE FASE E ESPACIAL TEMPORAL PARA TRANSMISSãO POR UMA PLURALIDADE DE ANTENAS". A presente invenção apresenta um método e aparelho para codificar os sinais em salto de fase e espacial temporal para transmissão em múltiplas antenas (160, 162, 164, 166). O método e aparelho provêem a expansão do código de bloco espacial temporal N x N<39> para o código de bloco espacial temporal M x M<39>, onde M>N, usando o salto de fase nos símbolos dentro do código de bloco espacial temporal N x N<39> para permitir a transmissão do código de bloco espacial temporal em um número de diversidade de antenas maiores do que N<39>. O resultado da diversidade de antena pode ser alcançado para transmitir M antenas.
