Abstract

"MéTODO E APARELHO PARA TRANSMISSãO E RECEPçãO DE DADOS". Várias versões são descritas para prover a transmissão e a recepção de dados de uma maneira melhorada. A transmissão de dados é melhorada ao incluir em um transmissor um gerador nulo (110) para gerar uma seqüência de símbolos de dados de saída que exibe nulos no domínio de freqüência em freqüências particulares que uma seqüência de símbolos de dados de entrada não exibe. Um insersor piloto (120) então acrescenta uma seqüência de símbolos piloto a esta seqüência de símbolos de dados de saída para criar uma seqüência de símbolos combinada. Como a seqüência de símbolos piloto exibe sinais piloto correspondentes aos nulos da seqüência de símbolos de dados de saída no domínio de freqüência, a seqüência de símbolos combinada exibe pilotos que são ortogonais aos dados no domínio de freqüência.
