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."METHOD AND APPARATUS FOR ENCODING SIGNALS IN STAGE AND SPACE JUMPS FOR TRANSMISSION BY AN ANTENNA PLURALITY". The present invention provides a method and apparatus for encoding the phase and time space jump signals for transmission on multiple antennas (160, 162, 164, 166). The method and apparatus provide for the expansion of the temporal spatial block code N x N <39> to the temporal spatial block code M x M <39>, where M> N, using the phase jump in symbols within the block code. N x N <39> to allow transmission of the temporal spatial block code over a number of antenna diversity greater than N <39>. The result of antenna diversity can be achieved to transmit M antennas.
