Abstract

sistemas e técnicas são reveladas para reduzir overhead piloto por fornecer sinais de referência comuns codificados com códigos de cobertura que são ortogonais em domínios de frequência e tempo. sinais de referência comuns que são codificados por códigos de cobertura ortogonais nos dois domínios podem ser desespalhados nos domínios tanto de tempo como de frequência para resolução aperfeiçoada e janelas de captura maiores. espaçamento piloto semi-uniforme nos domínios tanto de frequência como tempo pode ser utilizado. em domínio de tempo, um primeiro par de símbolos piloto é espaçado por um primeiro intervalo de tempo e um segundo par de símbolos piloto é espaçado por um segundo intervalo de tempo a partir do primeiro par, o segundo intervalo sendo maior que o primeiro. no domínio de frequência, um primeiro conjunto de símbolos piloto é densamente colocado em uma banda de frequência selecionada e um segundo conjunto de símbolos piloto é escassamente colocado circundando e incluindo a banda de frequência selecionada.
