Abstract

TRANSMISSãO DE DADOS COM ESPALHAMENTO ESPACIAL EM UM SISTEMA DE COMUNICAçãO MIMO Para transmissão de dados com espalhamento espacial, uma entidade de transmissão (1) codifica e modula cada pacote de dados para obter um bloco de símbolo de dados correspondente, (2) multiplexa os blocos de símbolo de dados correspondente, (2) multiplexa os blocos de símbolo de dados em N ~ s~fluxos de símbolo de dados para transmissão em N ~ s~ canais de tramissãoes de um canal MIMO, (3) espalha espacialmente as N ~ s ~ fluxos de símbolo de dados com matrizes de direcionamento,e (4) processa espacialmente N ~ s ~ fluxos de símbolo espalhados para transmissão CSI total em N ~ s ~ automodos ou transmissão CSI parcial em N ~ s ~ canais espaciais do canal MIMO. Uma entidade de recepção (1) obtém N ~ r ~ fluxos de símbolos recebidos atráves de N ~ r ~ antenas de recepção, (2) realiza o processamento espacial de receptor para a transmissão CSI total ou transmissão CSI parcial para obter N ~ s ~ fluxos de símbolo detectados, (3) desespalha espacialmente as N ~ s ~ fluxos de símbolo detectados com as mesmas matrizes de direcionamento utilizadas pela entidade de transmissão para obter N ~ s ~ fluxos de símbolo recuperados, e (4) demodula e decodifica cada bloco de símbolo recuperado para obter um pacote de dados decodificado correspondente.
