Abstract

APARELHOS DE RADIOTRANSMISSÃO E DE RADIORRECEPÇÃO, E, MÉTODO PARA TRANSMISSÃO DE DADOS. É descrito um aparelho de radiotransmissão que inclui uma pluralidade de antenas de transmissão, uma unidade de geração símbolo de início 2 que gera um símbolo de início como um sinal de referência durante o início da codificação diferencial, uma unidade de codificação diferencial (uma unidade de codificação diferencial 3, uma unidade de cálculo da energia do sinal de transmissão 6 e uma unidade de operação de 1/raiz quadrada 7) que sujeita um símbolo de transmissão, para o qual bits de informação são mapeados, a codificação diferencial e gera um símbolo depois da diferenciação e uma unidade de decodificação de espaço-tempo 8 que sujeita o símbolo de início ou o símbolo depois da diferenciação a codificação de espaço-tempo e gera sinais a serem transmitidos a partir das antenas de transmissão. A unidade de codificação diferencial determina, com base na energia elétrica do símbolo de início ou na energia elétrica do símbolo depois da diferenciação gerado na última vez, a energia elétrica do símbolo depois da diferenciação gerado no processamento de codificação diferencial atual.
