Abstract

"TRANSMISSãO DE REDUNDáNCIA INCREMENTAL PARA MúLTIPLOS CANAIS PARALELOS EM UM SISTEMA DE COMUNICAçãO MIMO". Para transmissão de redundância incremental em múltiplos canais paralelos em um sistema mimo, um transmissor processa (por exemplo, codifica, particiona, intercala e modula) cada pacote de dados para cada canal paralelo com base em uma taxa selecionada para o canal paralelo e obtém múltiplos blocos de símbolos para o pacote. Para cada pacote de dados, o transmissor transmite um bloco de símbolos de cada vez em seu canal paralelo até que um receptor recupere o pacote ou todos os blocos tenham sido transmitidos. O receptor executa detecção e obtém blocos de símbolos transmitidos nos canais paralelos. O receptor recupera os pacotes de dados transmitidos nos canais paralelos independentemente ou em uma ordem designada. O receptor processa (por exemplo, demodula, deintercala, remonta e decodifica) todos os blocos de símbolos obtidos para cada pacote de dados e provê um pacote decodificado. O receptor pode estimar e cancelar interferência devido aos pacotes de dados recuperados de modo que pacotes de dados recuperados posteriormente possam obter SINRs mais elevadas.
